Boker Plus Sulaco Knife Review

Boker traces its origin to the 17th century as a tool maker in Germany graduating to swords and blades by the 1800s. The company claims it was producing 2000 sabres a week by 1839 for use in various wars. By the 1860s the company had fractured with a branch of the family emigrating to North America and setting up plants in Canada, New York, and Mexico. The German and North American factories produced similar knives and used the “Tree Brand” trademark. This continued until World War II when the Solingen factory was destroyed and Boker USA took control of the trademark until the German factory was rebuilt in the 1950s. In the 1960s and 1970s the company changed hands several times, with the New York facility shutting down in 1983. In 1986, Boker reacquired the rights to the American brand and Boker USA was started in Denver, Colorado for US production.

Boker USA actually has four lines of knives that they produce. The first one is the Boker Premium Collection that focuses on high-quality, handmade sports, and collectible knives form the Boker manufacture in Solingen. The next line is the Boker Tradition—these are handmade hunting and leisure time knife from the Boker knife manufacture in Buenos Aires. Third is Magnum by Boker which focuses on Price and Performance—this line focuses on attractive sports and leisure time knife for the daily use and collectible swords. The last line is the Boker Plus line. This is the line of knives that produces the Sulaco knife. This line is in close cooperation with international acknowledged experts form military, police, and security to develop and test tactical knives for the professional user. Boker Plus knives are innovative in terms of function and design, as well as guaranteed for everyday use. Conception, design, and construction of these knives are carried out in Solingen, and production takes place in Europe, the USA, and Asia.

Today we are going to focus on the Boker Sulaco Titanium Folder knife with a stonewashed blade.

The Blade:

The blade on this knife is made out of 440C stainless steel. 440C is a 400 series stainless steel and it is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58-60 HRC. It is a bearing steel and is used to make knife blades. This is an upper mid-range steel that was once considered the high-end in US knife steels, 440C is a good all-around steel that has now been overshadowed by many of the newer super-steels on the block, although that does not take away from the qualities that it still possesses. This is a stainless steel that is most commonly found on mass-manufactured pocket knives and is so popular because it is a solid, affordable, all-around choice. This steel is reasonably tough and wear resistant, but it excels most at how stain resistant it is. This steel does hold an edge better than its 400-sereis counterpart 420HC but, you do lose some of its corrosion resistance. This steel can easily be sharpened. It does have the highest levels of carbon and chromium in 400 series of stainless steels. This steel does have good resistance to the atmosphere, fresh water, and mild acids. It has the best resistance in the hardened, tempered, and passivated condition. This steel allows for razor sharp edges.

To create this finish, the blade starts with a dark wash to give the blade an initial protective finish Then the blade is washed with stones, or literally rolled around with pebbles, which marks it, bringing out the underlying color of the steel. The finished stone wash gives the knife an interesting pattern, while still maintaining the protective properties of the dark wash. This finish helps hide wear and tear on the knife as the knife is used. One of the stonewash finishes biggest advantage is that it preserves the look of the blade overtime. The stonewash finish gives you a textured, rugged look. This blade finish helps to hide scratches and fingerprints, so you won’t have to polish your blade as often as you would with other blade finishes. Also, depending on the manufacturer, a stonewash finish can often look satin from a distance.

This blade has been carved into a spear point style blade. This style of blade is very similar to the needle-point style of blade, because of how good it is for piercing. But, the spear point does have a stronger tip and it does contain a small belly that can be used for slicing, unlike the needle point blade shape. The spear point shape is a symmetrically pointed blade with a point that is in line with the center line of the blade’s long axis. Both edges of the knife rise and fall equally to create a point that line sup exactly with the equator of the bade. The spear point blade shape is a great choice if you are looking for a good balance between piercing and slicing ability. This blade shape combines the sharp point of a dagger with the strength of a drop point blade, while also maintaining some of the “belly” that is used for slicing. All in all, it is a great hybrid blade design that is extremely functional. With this blade, the point controllability is excellent and the point is extremely strong, so you can easily use this knife for detail and tip work. To help with overall controllability, the entire spine of the knife has thick, shallow jimping. This gives your fingers a little bit of grip to really have full control over your blade at all times and in all environments. This blade does sport a plain edged blade, which gives you the ability to use this knife in a wider variety of tasks. However, some people do love the serrated edge because they with a serrated edge you can saw through some of the tougher and thicker materials. On the other hand, serrated edges leave you with jagged cuts, while a plain edge will give you clean cuts and slices.


The Handle:

The handle on this knife is made out of titanium. Titanium is truly a phenomenal material for knife handles. For how light the material is, it is amazing how durable and tough it is. On the flip side, it is also the most expensive common metal used in knife handles. It offers an extremely high resistance to corrosion, it doesn’t conduct and retain cold as much as its counterparts, and it can be anodized just the same as aluminum. Surprisingly, titanium is actually less resistant to scratching than stainless steel, but the upside of lightness outweighs the downside.

Some of the pros of this material is that it is strong—titanium is ideal for high-end, high performance knives and gear because it is light and strong. Titanium has a very high tensile strength. The next advantage is that it is low weight—titanium has a very low density. This characteristic strength to weight ratio is absolutely crucial when making a decision on your everyday knife. Titanium is also very corrosion resistant—it is even resistant in saltwater environments; this trait is due to a continuous oxide outer layer when exposed to air. Unfortunately, with all of those pros, titanium will cost you a decent amount.

A rare characteristic of titanium is that it is one of those rare metals that has a warm feel to it, so it won’t make your hands suffer nearly as much in the winter time, especially when being compared to aluminum.

The handle on this Boker knife has a very deep finger groove with a shallower finger groove following it, to give you a very comfortable and safe grip. There is jimping on the spine of the knife as well as a small portion on the bottom of the handle. The handle is two-toned; with lighter grey in the middle and darker grey framing it. Across the palm of the handle, there is a lot of thick texturing to give you a very secure grip. And, as a bonus and a benefit to using this as your EDC of choice, there is a lanyard hole carved into the butt of this handle.


The Pocket Clip:

The pocket clip on this knife is statically designed for tip up carry only on the traditional side of the handle. This is a deep carry pocket clip in a stonewash finish. This clip is kept in place by two small silver screws that match the rest of the hardware on the Boker Sulaco.


The Mechanism:

This is a manual folding knife that uses dual-thumb lugs and a frame lock design. A thumb lug is just a large thumb stud. This is arguably the most common one-hand-opening feature, and you can find this opening system through most knife manufacturers. A thumb lug essentially replaces the nail nick found on more traditional knives. The principle is pretty straightforward—you grasp the folded knife, place the tip of your flexed thumb on the stud and extend your thumb to swing the blade through its arc until the blade is fully open. Because the thumb lugs extend through both sides of the blade, the knife becomes ambidextrous.

The locking mechanism that this knife is equipped with is a frame lock mechanism. You can think of a frame lock as a beefed up version of the liner lock. They are very similar to liner lock mechanisms, except instead of an internal spring bar moving into place, tis part of the handle itself. Frame lock knives tend to be stronger than liner locks, as the piece of metal that slips into place is more substantial than that in a liner. Because of their similarity to liner locks, closing a frame lock knife is virtually the same—you push down on the spring bar so it no longer blocks the butt of the blade, remove your thumb from the path, then fold the knife closed.

This type of locking system puts a large portion of metal against the blade, ensuring a strong lockup for piercing, cutting, slicing, and other heavy duty tasks. Frame locks are seen in lots of mid to upper range knives, typically rafted from titanium. Frame locks are known for their strength and thickness, but it is only with the correct construction that they operate at full capacity. In the angle of the blade bottom is not matched correctly with the lock, the lock may not travel the correct distance, damaging its effectiveness.


The Specs:

The blade on the Boker Sulaco measures in at 3.7 inches long with the handle measuring in at 4.8 inches. The overall length of the knife is 8.5 inches long. This knife weighs in at 4.8 ounces.



Ram Maramba, late owner/operator of Zero Knives, is a Texas-born knife maker who was remembered for his contemporary non-nonsense forms and eye-catching conceptions. Each frame lock designed model sports a milled handle that is not only aesthetically pleasing but promotes plenty of grip security. Couple that with the dual over-sized thumb lugs and this folder is ready to go right out of the gate. The Boker Plus line of knives are designed in cooperation with knife experts worldwide and provide innovative knife concepts for every task. This model features an all-titanium handle, a modified spear point style blade in a stonewash finish and the pocket clip is statically designed for tip up carry only on the traditional side of the handle. The titanium handle is strong and durable, so you can take on all of your heavy duty tasks that come your way throughout your day. The spear point blade style is the perfect balance between point strength and belly, which helps with versatility. The stonewash finish and 440C stainless steel help preserve the look of your knife, because both of them are low maintenance.

Boker Magnum Automatic Knife Review

Boker is one of the oldest knife manufacturers around, dating back clear into the 17th century. Boker says that “a huge chestnut tree towering above the small Boker hardware-factory in eh 17th century is the oldest traceable fact about the Boker family. Apparently Boker tools were very successful, for they ranked among the leading products in Germany and neighboring countries a hundred years later.”

In 1829, there was a rising demand in a politically restless era. Hermann and Robert Boker decided to start with the production of sabres in 1829. Inventories of September 1830 already prove a weekly production of 2000 pieces, made by 64 smiths, 47 grinders, and a large number of laborers. With an ever growing variety of tools and cutlery combined with the possibilities of international marketing the family realized that responsibility assignment was crucial to keep their chances. So Hermann Boker emigrated to found Boker & Co in New York, whereas the younger Robert established his company in Canada in 1865, and later a branch in Mexico.

Heinrich only cross the river Wupper to go to Solingen, where the German cutlery industry was booming, to found Heiner. Boker & Co. with the well-known cutlery expect Hermann Heuser in 1869.

The Bokers in Remscheid and their cousins overseas were very interested and in demand of razors, scissors, and pocket knives from Heinrich’s new enterprise. They had to label their products in a simple manner for overseas-markets, for many customers had problems spelling the German name Boker. Heinrich considered the chestnut tree as an ideal memorable logo, which belonged to the Remscheid company with another one, an arrow. One of the rare and precious documents, which survived the total destruction of WWII is an ad of Boker Remscheid form 1874, showing both logos.

The relationship between the two Boker companies has always been very friendly. Heinrich was allowed to take the tree-brand with him across the river without troubles or payments. Since then not a single product has left the Solingen factory without this sign. After over 100 years of existence the venerable tree was cut down by a stroke of lighting in 1925. A gifted artist carved an image of the majestic tree into a piece of original tree trunk, which adorns the executive’s office in Solingen.

The US market actually became the main customer of Boker production as early as 1900 with H. Boker & Co in New York concentrating on Solingen cutlery. The demand for pocket knives soon beat that for other products like scissors or razors. In due course, the Solingen capacities were exhausted and the New Yorkers started their own pocket knife production. Because of the tree-brand being well established by then and the good understanding within the international Boker family, there wasn’t any problem to get permission from Solingen to use the tree-brand for American products too. Since then, there were two different lines of Boker knives son the US market, with identical logos and sometimes even identical item numbers, one line made in USA, the other made in Solingen. The only distinguishing characteristic is the markings “Boker USA” or “H. Boker Improved Cutlery Solingen.”

With such a rich history, you can expect rich, high quality knives. Today, we will be talking about the Boker Magnum.


The Blade:

The blade on this knife is made out of AUS-8 stainless steel. This is an upper mid-range steel. AUS-8 steel is Japanese made and extremely similar to 440B steel which is slightly more resistant to rust and corrosion than 440C but less hard. It’s also similar tough but may not hold its edge as well as some of the more premium steels which carry a greater degree of carbon. Remember, more carbon means more hardness and edge holding. This steel is really easy to sharpen and does take a razor sharp edge. This is one of the more common stainless steels, and it is one readily available in lots of different places worldwide. This is a decent all around steel. It is hard enough, tough enough, and stain resistant enough. It will not hang long with high end powder metal steels, but among the steels you are going to find on most knives, this is a pretty good choice.

The blade has been finished with a black coated finish. Coatings provide corrosion resistance, but they will scratch off eventually and at different rates, depending on the quality of the coating. Coated finishes are completely matte and reduce glares and reflections, while also reducing wear and corrosion. Coatings can prolong the life of a blade by preventing corrosion or rust. Quality coatings do add cost to a knife, but will provide more corrosion resistance, less reflection, and even require less maintenance.

Boker Magnum Auto Knife, Tanto
Boker Magnum Auto Knife, Tanto

The Boker Magnum has been carved into a tanto blade shape. The tanto blade shape is the perfect option if you don’t want an all-purpose knife. This blade shape is designed for doing one thing and that one thing really well. The thing that the tanto excels at is piercing through tough materials. This style of blade was originally designed for armor piercing, the tanto blade was popularized by Cold Steel and is similar in style to Japanese long and short swords. The tanto knife has a high point with a flat grind, leading to an extremely strong point that is perfect for stabbing into hard materials. The thick point of the tanto blade contains a lot of metal near the tips, so it is able to absorb the impact form repeated piercing that would cause most other knives to break. The front edge of the tanto knife meets the back edge at an angle, rather than a curve. As a result, the tanto blade does not have a belly, which is sacrificed in exchange for a stronger tip. Because it does lack a belly for slicing, it is not useful as a general utility knife. However, its extremely strong point allows it to be used in tough situations where piercing hard materials is required. When you choose this knife, you are choosing a knife that is specifically tailored to piercing tough materials.

This knife does feature a combo blade edge. This edge style is where the top portion of the blade is a plain edge and the bottom portion of the blade is a serrated edge. This style of blade edge has actually overtaken the all-serrated format. There are plenty of mixed feelings on this format. Many people actually swear by this format, and feel that it is a good compromise, giving the user the choice of precise push cuts form the plain edge, and the advantage of the serrated edge for tougher materials. However, because the edge is split, some people feel like the serrated portion is too short for the serrations to really be useful and the length of the plain edge is being sacrificed for no good gain. Really, when choosing a knife with a combo edge, it comes down to solely preference. There are plenty of good things to a combo edge, but there are also a few drawbacks. I would recommend looking at what you expect to be doing with this knife to see if it is a good option for you and your lifestyle.


The Handle:

The handle on the Magnum has been made out of aluminum. This aluminum has been anodized black, not only for color, but also for hardness and protection. Aluminum is a very durable material for knife handles. It is in the category of low density metals, but it still has the hefty feel to it, without actually weighing the knife down. This balance is hard to achieve because you want the knife to feel hefty enough to take on your daily tasks, but you don’t want your knife to weigh you down, like a steel handle would. When this material is texturized correctly, it can provide you with a reasonably secure grip that is also comfortable and easy for extended use. Unfortunately, one of the biggest disadvantages is that if you are using your knife quite a bit during colder winter months, you might find the handle uncomfortably cold given its conductive properties. Aluminum is generally considered inferior to its stronger, yet more expensive brother Titanium, which tends to be found on the more premium knives. One of the other drawbacks to this handle material is that it is susceptible to scratches and dings.

The ergonomics of this handle are excellent. The handle curves to fit in your palm smoothly and comfortably, even if you are using this knife for long periods of time. The butt of the handle is flared out slightly and three are grooves cut in down the palm of the handle to provide you with exceptional grip.


The Pocket Clip:

The pocket clip has been designed for tip down carry only. The clip is mostly straight, but the portion that is screwed into the handle does curved to match the curves of the handle top. The clip is black, matching the rest of the knife and three black screws keep it held in place.


The Mechanism:

This is an automatic knife. Automatic knives do have a series of strict laws surrounding them in the United States. They are not legal in all states, cities, or areas. Make sure that you are certain about your local laws before purchasing and carrying this knife, because it might be illegal to carry. Automatic knives are also known as switchblades. This is a type of knife with a folding or sliding blade contained in the handle which is opened automatically by a spring when a button on the handle is activate. Most switchblade designs incorporate a locking blade, in which the blade is locked against closure when the spring extends the blade to the fully opened positon. The blade is unlocked by manually operating a mechanism that unlocks the blade and allows it to be folded and locked in the closed position.

There are plenty of advantages to having an automatic knife such as that they are fast and you can even open them one handed. Some of the disadvantages are that there is restricted ownership, they are usually more expensive, and since there are so many mechanical pieces, something could break and then the knife wouldn’t work. If you are in a tactical situation, an automatic knife is going to be a great option because they do have crazy fast blade deployment. However, while automatic knives are extremely fast to deploy, they are also typically slower to close.


The Specs:

The blade on the Boker Magnum is 3.25 inches long. The overall length of the knife is 8 inches long, with the handle measuring in at 4.75 inches long. The knife weighs in at 4.4 ounces. When you order this knife from BladeOps, the seals on the box will arrive broken due to the knife being converted in our shop.



The Boker Magnum automatic knife is one of the more popular side open automatics on the market today considering the price point. This knife is referred to an auto-conversion knife which means the knife is produced as a folder knife and then converted via third party to offer the automatic function. The Magnum series features an aluminum handle scale that is comfortable and ergonomic and the AUS-8 blade material offers better edge retention than you would expect. The aluminum handle is extremely durable and resistant to rusting or corrosion. The AUS-8 is a quality, all-around steel that is going to be able to take on almost all of your daily challenges. With a knife made out of both of these materials, you can expect a knife that is going to step up to the plate and succeed under pressure. This particular model features a black handle with standard hardware and a tanto blade, that is partly serrated, in a black finish. Finally, the pocket clip is designed for tip down carry only.

The Boker Plus 01BO777 Lateralus Knife Review

Boker has been around since the 17th century. There was a huge chestnut tree towering above the small Boker hardware-factory in the 17th century, which is the oldest traceable fact about the Boker family. For hundreds of years, it seems as if Boker tools have been successful and ranked among the leading products in Germany and spreading to the neighboring countries and then worldwide hundreds of years later.

It was due to rising demand in a politically restless era Hermann and Robert Boker decided to start with the production of sabers in 1829. Inventories of September 1830 already prove a weekly production of 2000 pieces, made by 64 smiths, 47 grinders, and a large number of laborers. With an ever growing variety of tools and cutlery combined with the possibilities of international marketing, the family realized that responsibility assignment was crucial to keep their chances. So Hermann Boker emigrated to found Boker & Co. in New York, whereas the younger Robert established his company in Canada and 1865 a branch of it in Mexico.

The Boker’s in Remscheid and their cousins overseas were very interested and in demand of razors, scissors, and pocket knives from Heinrich’s new enterprise. They had to label their products in a simple manner for overseas-markets, for many customers had problems spelling the German name Boker—apart from widespread analphabetism. Heinrich considered the chestnut-tree as an ideal memorable log, which belonged to the Remscheid company with another one, an arrow. One of the rare and precious documents, which survived the total destruction of WWII is an ad of Boker Remscheid from 1874, showing both logos.

On Boker’s website, they say, “The relationship between the two Boker companies has always been very friendly. Heinrich was allowed to take the tree-brand with him across the river without troubles or payments. Since then, not a single product has left the Solingen factory without this sign.

A gifted artist carved an image of the majestic tree into a piece of original tree trunk, which adorns the executive’s office in Solingen.”

Within the Boker Brand, there are four different lines. They have the Premium collection, the Boker Arboltio—which is the tradition collection, Boker Plus—which is the innovation collection, and lastly Magnum by Boker—which is Price and Performance.

The Lateralus is part of the Boker Plus line. The products in this line are in close cooperation with international acknowledged experts from military, police and security as they develop and test tactical knives for the professional user. Boker Plus knives are innovative in terms of function and design, as well as guaranteed for everyday use. Conception, design, and construction are carried out in Solingen, and production takes place in Europe, the USA, and Asia.


The Blade:

The blade on this knife is made out of D2 Tool Steel. This steel is used in industrial settings. It has a high hardness and relatively high toughness that make it an excellent choice in the industrial setting and in cutlery. While it is technically not a stainless steel, it is relatively corrosion resistant. This steel is considered a “semi stainless” as it falls just short of the required amount of chromium to qualify as full stainless. D2 has been around for more than 20 years, which is considered an eternity in metallurgy terms. Over the years, different heat treats have emerged, but one has risen to the top as the best—Bob Dozier’s D2. Despite its age, it is a truly superior steel. D2 steel is much harder than other steels in the same category such as 154CM or ATS-34, and as a result, it does hold its edge a little better. With that being said, it is not as tough as many other steels and is exponentially tougher to sharpen. In fact, you will most likely need to be a master sharpener to get a fine edge eon D2 steel.

The Lateralus has been finished with a stonewash finish. A stonewashed finish refers to tumbling the blade in an abrasive material. This finish easily hides scratches, while also providing a less reflective nature than a brushed or satin finished blade. There is a wide variety of stonewashed finish based upon the abrasive shape, tumbling motion, and the type of finish the blade has before it entered the tumbler. One of the very positive benefits of a stonewashed blade is that it is a very low maintenance finish and it easily preserves the original look of the blade overtime. A stonewash finish also hides fingerprints pretty well, so the blade might not need to be polished as often as others with different finishes. The stonewash finish provides the knife with a very rugged, well-worn look. Depending on the manufacturer, a stonewash finish can often look satin from a distance.

The blade has been carved into a drop point style blade. This is a great all-purpose knife that can stand up to almost anything. This shape is also one of the most popular blade shapes that is in use today. The most recognizable knife that features a drop point is the hunting knife, although it is used on many other types of knives as well, including the larger blades in Swiss army knives. To form this shape, the back edge of the knife runs straight form the handle to the tip of the knife in a slow curved manner, which does create a lowered point. It is this lowered point that provides more control and adds strength to the tip. While the tip on a drop point is not as sharp as the tip on a clip point, it is much stronger. It is because of this tip strength and the ability to hold up to heavy use that makes drop point blades a popular blade shape on tactical and survival knives. Drop point knives feature a large belly area that tis perfect for slicing. One of the only real disadvantages the drop point blade is its relatively broad tip, which makes it less suitable for piercing than the clip point. However, this broad tip provides point strength that is not found on the similar clip point knives. When you choose this knife, because of the drop point, you are equipping yourself with a blade that reacts well in many situations.

The Lateralus does sport a plain edge, which will give you very clean cuts. This plain edge will also be able to take on a wide variety of tasks—more tasks than a serrated or combo edge would be able to complete. The plain edge is easier to sharpen and you will also be able to get a finer edge on it.

On the spine of the blade, there is a row of thick, shallow jimping to help you have complete control over your cuts.


The Handle:

The handle of this Boker knife is made out of G10 and stainless steel. The front handle scale is G10. G10 is a grade of Garolite that is a laminate composite made of fiberglass. It has very similar properties to carbon fiber yet can be had for almost a fraction of the cost. To make this material, the manufacturer takes layers of fiberglass cloth and soaks them in resin, then compresses them and bakes them under pressure. The material that results is extremely tough hard, very lightweight, and strong. G10 is actually the toughest of all the fiberglass resin laminates and stronger, although more brittle, than Micarta. G10 is durable and lightweight, but

Boker Lateralus
Boker Lateralus

still non-porous. These qualities make it a phenomenal choice for tactical folder and fixed blades, because it is in these genres that things are going to messy. The G10 on the front handle scale is black.

The back handle scale is made out of stainless steel. This material provides excellent durability and resistance to corrosion, but it is not lightweight. Also, stingless steel can be slippery. Because it is combined with the G10 handle scale though, the weight won’t be an issue and the G10 will give you a secure enough grip. Stainless steel is strong and durable.

For the texturing and solid grip, Boker has a series of grooves going down the palm of the handle. The shape of this handle is a unique one. The handle is much skinnier at the top of the knife, where the blade and handle meet. There is a deep, elongated finger groove carved out of the bottom part of the handle. This finger groove is going to give you a secure, comfortable grip on this knife. The butt of the handle is rectangular, but it does have an angled portion. It is on the angled portion that the knife features the lanyard hole.


The Pocket Clip:

The pocket clip on this knife is statically designed for tip up carry only on the traditional side of the handle. The clip is on the stainless steel handle scale, so it is stainless steel. This clip is kept in place by two small, silver screws, which do match the rest of the hardware on the Lateralus.


The Mechanism:

This knife features a flipper mechanism. This is an assisted-opening knife which means that it is a type of folding knife which uses an internal mechanism to finish the opening of the blade once the user has partially opened it using the flipper. When the knife is in the closed position, the blade is held in place by means of torsion springs and an additional blade lock. As the user applies manual pressure to the flipper, a mechanism such as a torsion spring moves along a track in the liner and rapidly rotates the blade into the open and locked position. Although commonly confused with switchblade knives, a switchblade can be opened automatically simply by the push of a button, but the user of an assisted-opening knife must open it about one quarter of the way before the mechanism opens the knife the rest of the way. The difference is important legally because the blade does not simply open by the push of a button or by the force of gravity, the assisted opening knife is typically not considered a switchblade and may escape the restrictions applying to those in many places.

The flipper mechanism is a square shaped protrusion that juts out of the pine of the handle when the knife is closed. You pull back on this piece of metal and it flips the knife open and locks it into place. The blade is deployed by using the index finger to pull back on it. This not only keeps your hands at a safe distance from the blade but gives you an added finger guard once opened. The flipper in most cases, including this one, will actually wing around and end up underneath the knife continuing to offer protection form accidental knife injuries. If you are concerned with the safety of your thumb, a flipper knife will be more to your liking.


The Specs:

The blade on this knife is 3.7 inches long with an overall knife length of 7.9 inches long. The handle of this Boker Plus knife is 4.2 inches long. This knife weighs in at 3.7 ounces.



The Lateralus is a Jason Stout designed flipper model that is a distant cousin to the Lucas Burnley designed Kihon–but with alternative styling, a longer blade and a lighter frame. Each frame lock designed model features a tool steel blade that is deployed with the spine flipper function and operates quick and fluid-like thanks to the ball bearing pivot. Stout also added his own personal flair–outfitting the Lateralus with a massive blood groove and the deep finger groove allows for accurate precision work. The Boker Plus line of knives are designed in cooperation with knife experts worldwide and provide innovative knife concepts for every task. This model features a black G-10 front handle scale, a stainless steel back handle scale, a drop point style blade in a stonewash finish and the pocket clip is statically designed for tip up carry only on the traditional side of the handle.

Boker Plus Tactical Kwaiken Knife Review

Kwaiken History

Anciently, Japanese women and men of the samurai class once carried the kwaiken blade. Primarily used for self-defense in indoor spaces, the kwaiken had an advantage over the long blade katana and intermediate sword wakizashi in smaller spaces. Women carried them in their kimono, either in a pocket-like space (futokoro) or in the sleeve pouch (tamoto), for self-defense purposes.

Today, the modern kwaiken also serves as a great self-defense tool for men and women everywhere. Its slim profile, and durable design are perfect in this realm.

Even though this blade has been around for many generations, it is best to cover the basics of the knife and the new modernized additions to the Kwaiken.


Burnley Design

Burnley Knives was founded in 2003 by Lucas Burnley in Albuquerque, New Mexico. Their mission is to “create custom knives with a superlative level of design and function utilizing ever evolving techniques and materials.” Much of Burnley’s inspiration comes from spending time with his father, time out among Mother Nature, and action packed survival stories and films. Over the years, he has experimented with a range of styles to combine classical knife designs with modern materials and techniques.



The Boker Kwaiken opens with a “flipper.” The flipper is that part of the blade that protrudes near the knife spine when the blade is closed. One advantage to having a flipper is when the blade is opened, it acts as an additional finger support when gripping the handle. It also, depending on the size, can serve as an extra way to protect your fingers when cutting. When proficiently skilled, a user can open a flipper knife in the blink of an eye. As the user pulls back on the flipper blade protrusion, the ball bearings rotate so that the blade glides out of the handle then locks into place, ready for use. Without the use of a spring or torsion bar to assist the blade out of the handle, the IKBS opening system is a manual opening system that provides a smooth, easy blade opening.


IKBS Ball Bearing Pivot System

One of the new twists to the Boker Kwaiken is the IKBS System. The Ikoma Korth Bearing System (IKBS) is a ball bearing pivot system for folding knives. The IKBS gives an exceptionally fast and smooth opening and closing action without much friction. The pivot requires very little maintenance and has a long service life. It works is by using uncaged ball bearings at the pivot which are held in grooves machined into the folder frame and blade. The IKBS was originally designed to fit in balisong knives, but because of its versatility it can be used in most kinds of folding knives (mainly liner locks and frame locks).
The IKBS system is highly favorable because of its simplicity.
An ordinary bearing is designed to rotate at high-speed for a long period of time and usually with some load applied on it. This required additional hardware such as bearing races and cages. With a simple flipper knife, such as the Boker Kwaiken, it was possible to eliminate those bulky and complex pieces, leaving just the steel balls to rotate the blade. Instead of external races, there are recesses made in the liners to hold the steel balls. And the pivot pin is used as the internal race. The steel balls that make up the IKBS are inexpensive and can be easily replaced without the need of any adjustment, making maintenance quite simple. The IKBS system is slightly adjustable. If any blade play occurs after time, tightening the pivot screw can easily eliminate it.
Blade Style

If you want a knife with a relatively narrow point and yet a curved belly, a straight back blade is the one for you. It is well suited for both thrusting and cutting. There isn’t too much of difference between a straight back and a dropped point. However, a straight back blade is the simplest of blade shapes. The sharp edge starts near the handle and curves towards the tip of the blade. The unsharpened edge continues straight from the handle to the tip. Simple, no? Having a straight back on your knife blade helps improve the strength of the blade. It also makes it ideal for adding thumb pressure when slicing and chopping. The straight dull back won’t hurt your thumb when adding a lot of pressure.


Blade Steel

VG-10 Steel isn’t a common steel you hear about. Though it is not used much, the blade steel is still excellent in quality. Sticking with the Japanese theme on the Boker Kwaiken, VG-10 is a cutlery grade stainless steel was originally designed and produced by Takefu Special Steel Co. Ltd., in Japan. It is a high carbon stainless steel containing 1% Carbon, 15% Chromium, 1% Molybdenum, 0.2% Vanadium, 1.5% Cobalt, and 0.5% Manganese. Even though carbon only makes up a relatively small amount of the total material of the blade, it is still a significant amount for stainless steel. The G in the name stands for “gold,” referring to the “gold standard” that this stainless steel is considered to have met. One of the original uses of this steel was in the horticultural industry. This is because of its ability to make clean, grafting cuts. Thus it would not fray or destroy the vessels of the plant. VG-10 was originally aimed at Japanese chefs, but also found its way into sports cutlery. VG-10 is quite capable of retaining an edge, while still being rust resistant. It is preferred by many professional chefs. With VG-10, you also get the hardness of a carbon steel. It is more expensive when compared to other steels such as 440 steels, but is well worth it. All of these qualities of this steel make this knife great for everyday use, plus its ability to take abuse.


Liner Lock

The liner lock is one of the most prevalent locking systems used in the knife industry and is the locking mechanism on the Boker Kwaiken. It was invented and patented in 1980 by Michael Walker. A liner lock works by having a section of the liner spring inwards and wedge itself beneath the tang of the blade when it is opened all the way. This locks the blade open between the stop pin and the liner locking mechanism. The liner lock is easy to manufacture and reliable to use. The biggest advantage of the liner lock is the easy one-handed opening and closing. Most other locking methods are not as easy to close one-handed. This type of locking mechanism, in conjunction with the flipper, makes this knife perfect for one-handed use. Not only for right handed people, but for left handed people as well.



The handle on the Boker Kwaiken is full of mysteries, like its origin, that are waiting to be unlocked. Do not let its appearance deceive you. There is a lot more than meets the eye. The handle is quite slim. In fact, it is three quarters of an inch thick in its thinnest spot and grows to just under an inch thick near the pivot area. Though it is slender, its weight is very dense. In total, the knife weighs around four and a half pounds. For such a small knife, the Kwaiken has quite the hefty feel to it.

In addition to the slimness and weight of the Kwaiken, the handle also includes the specially fabricated handle scales. Made from a single G-10 piece, the lower part has a milled, wood-like texture for a neat design and a secure grip. The portion near the pivot is made without this texture to provide a contrasting look from the scales. This special look gives the knife a unique appeal while retaining a natural look.

G-10 or G10 is similar to Micarta and Carbon Fiber and is often used in handles because of its moisture imperviousness. G-10 is a fiberglass based laminate made by layers of fiberglass cloth that are soaked in an epoxy resin, are compressed, and then baked. The result is a material that is hard, lightweight, and strong. The surface of the G-10 is a checkering texture that is added for additional grip support. A unique property of the material is that the grip improves when wet. This material is difficult to break. It is also an ideal handle material because it does not shrink or swell in extreme hot or cold temperatures. Many knife companies prefer to use G-10 because of these properties, but also prefer to use it because it is easy to shape into different designs and has a possibility for an unlimited number of colors. This handle is recommended for knives that are to be used in survival situations. G-10 is considered the toughest of all the fiberglass resin laminates and stronger (though more brittle) than Micarta. Its main advantages include its toughness, its light weight, it is strong and durable, impervious to water, low maintenance, and relatively inexpensive. Though it can be brittle, and occasionally have a cheap plastic feel, G-10 is a fantastic handle material.


Everyday Carry

As an everyday carry knife, it is important to know how the Boker Kwaiken feels when being carried around all the time. Those criteria include its carry depth, its weight, its thickness and width, and its appearance.

Carry Depth

The Boker Kwaiken is comfortable to carry in your pocket. The slim design takes up minimal pocket real-estate. Because of its smaller size, it sacrifices the potential for a really secure and comfortable grip.  When closed, the knife is 4.88 inches long. You’ll find that most comfortable carry knives are anywhere between 3.5 to 5 inches long when closed. The knife rests just near the edge that range. Frequently, before any knife purchase, I ask myself, “Will the knife fit in my pant pocket?” But I also ask “Will the knife fall out of my pocket?” The knife is a deep carry knife. The pocket clip allows the majority of the knife to fit within my pocket.


One of the more important aspects to consider when choosing an everyday carry is its weight. One of the worst feelings that can happen on a day to day basis is carrying something heavy in your pocket. A good knife weight ranges anywhere from as little as 3.0 ounces to 5.0 ounces. The Kwaiken barely fits right into this range. It weighs 4.45 ounces. For the size of the knife, I would be careful about getting it if you are sensitive to your pocket weight. But again, it is within this range of comfortable weight. The knife is just dense.

Thickness and Width

Like we mentioned before, the knife is very slim. At most, the knife is just under an inch thick. And the knife is just under half an inch wide from handle scale to handle scale. There is hardly anything to the Kwaiken.


When the knife is closed, it looks pretty conservative, especially with its “wood grain” finish. But when the knife is unleashed, it does have that ancient samurai intimidation to it. It’s as if it says “Be careful, this knife will come after you.”



Boker is constantly coming up with knifes that work well for a decent price. At $135, you will be happy with this purchase. There are many creative minds going into this blade. From the creators of the IKBS System to Lucas Burnley, and from the people over at Boker to the ancient Japanese creators of the kwaiken, the Boker Plus Tactical Kwaiken is a huge hit. You will want this in your armory.


Boker Knives and Two Boker Plus Knives

Böker Knives began in Germany during the 17th century. The company originally focused on swords and didn’t move on to design blades until the 1800’s. If you go back and look at the company’s books, they will tell you that by 1839 Böker was producing around 2000 Sabres a week for various wars. In the 1960’s, the company had migrated into North America; however, they were just sub brands at the time. During World War II, the main Germany factory was destroyed, so Boker USA took control. Since then, the company has traded hands several times, but in 1986 Boker USA was started for good for US production. The symbol of this company is a giant chestnut tree, which is the perfect symbol because over the 150 years that it has existed, the company has reached out, or “branched out”, and become planted across the world.

Boker USA is the in charge of the production of Boker knives, but they carry five brand names underneath them which are Boker, Boker Arbolito, Boker Plus, Magnum by Boker, and Cinch by Boker.


Boker is sometimes known as the Tree Brand, so any knives that are labeled with this are usually purely Boker.


Boker Arbolito means little tree in Spanish. If you see a knife labeled with this name, it means that it was manufactured in Argentina and typically are only household or work knives.


Boker Plus knives are manufactured in Taiwan and China. These knives are typically not as high quality as Boker, but they are more quality than Magnum by Boker. In this line, you will find tactical and outdoor knives.


Magnum by Boker knives are also manufactured in Taiwan and China. This line of knives focus on value, so out of the five sub brands, these are going to be the least expensive of them. Don’t worry about sacrificing quality though, because these knives are still made from quality materials.


Cinch by Boker are knives designed to fit the Western lifestyle. They are targeted towards ranchers and outdoor enthusiasts. This is actually a collaboration between Boker and Cinch Jeans. This is a classy line that have an authentic feel to them.

Boker produces great knives and because of the five different sub brands, you will find a large variety of different styles, values, and designs of knives. Today I am going over two great and popular Boker Knives.



The Boker Plus Subcom:


Just like the name implies, this is part of the Boker Plus brand. The drop point blade on this knife is 1.875 inches long. The overall length of this knife is 4.625 inches long and has been known as the “money clip knife”. This knife has been used for a defensive tool and a backup knife. The blade has a big belly that makes it perfect for utility purposes and the tip is chubby so it isn’t meant for stabbing. Even though it is so small, because of the blade shape and the tip shape it can cut just as well as a larger knife.

The knife weighs 2.5 ounces, which seems small at first, but when you realize that the blade is smaller than 2 inches long, it starts to seem like a hefty knife. It weighs what it does because the knife has a stainless steel frame lock and a full steel liner.

The ergonomics on this knife is as good as you are going to get on such a small knife, because really, there is no way that you can fit your whole hand on this. A bonus about the handle on this knife is all the jimping, which provides grip and traction just where you need it. Unfortunately, because of all this jimping, it can be an uncomfortable knife to use for long periods of time.

This knife was such a hit that Boker made a few different versions to satisfy everyone, these versions are:


The Subcom F: This version has AUS-8 steel with a black or silver blade. It is partially serrated and has an FRN handle that comes in either black or gray. The locking system is a frame lock. This was the original Subcom knife and the other versions are just copycats. Along with the silver, black, and gray versions, there is a special camo version.


The Subcom Titan: When Boker designed this version, they designed it to be an elite version of the F. This version sports a satin 440-C stainless steel, which is a higher quality steel than the other versions. The edge is plain. The handle is made out of titanium and because of that it only weighs 1.9 ounces. Because of the titanium handle and silver blade, it looks more elegant than the other versions. It has either a frame lock or a slip joint locking mechanism.


The Subcom 42: This blade is made out of AUS-8 steel that is finished with a bead blast. The blade has a plain edge. The handle is made out of pink FRN material and it sports a frame lock mechanism.


The Subcom Dusk: This version also has AUS-8 steel, but this one has a black finish. It is partially serrated. The Zytel handle is orange and this version boasts a framelock mechanism.


The Subcom Dawn: This also has a satin AUS-8 blade that has a plain edge. The Orange Zytel handle has either a frame lock or a slip joint locking mechanism.


The Subcom Z: Just like most of the versions, the Z has AUS-8 steel, but with a black finish. It is partially serrated. The green Zytel handle sports a frame lock system.


The Subclaw: This version is very similar to the Subcom F but the main difference is the blade shape. This version has a Hawkbill blade. This blade shape is great for slicing, but not for a lot of other things. Many people only see this as a defensive or collectors blade.


The WharCom: This is also similar to the Subcom F, but again, it has a different blade shape. This style of blade has a Wharncliffe blade that is perfectly straight from the handle to the tip. The shape is very similar to a razor blade. This is a great blade shape for slicing, but it is a perfect blade shape for scraping.


The ResCom: This is the most unique out of all the Subcom versions that were previously mentioned. This one is designed for safety and rescue situations. It is also similar to the Subcom F. The ResCom has an almost hook shaped blade, but the outside of the hook is not sharp in any places. There is another portion of the blade that is a saw. This is so that you can cut materials that are too large to get through the hook. This is not going to be an everyday knife, but it is a great candidate for your emergency, safety, or rescue knife. It does dull relatively quickly, so using it for everyday tasks would not be ideal. You can get the ResCom in two different versions: all black—black blade, black handle, and black thumb studs, or a red version—silver blade, red frame and red thumb studs.


Pros of the Plus Subcom:

  • This is a very small knife, so it won’t weigh you down and is easy to have with you at all times.
  • The knife sports a large belly, so it is easy to cut with and can actually cut as well as larger knives.
  • The knife comes in a large variety of handle colors and materials.
  • The knife also comes in a large variety of steel and steel colors.
  • The extra jimping allows for great grip.


Cons of the Plus Subcom:

  • This is a tiny knife, so it can’t stand up to large, heavy duty tasks.
  • The extra jimping can get uncomfortable quickly.
  • There is no way that you are going to be able to use your hold hand to hold this knife.



The Boker Plus Kwaiken Flipper:


This knife is also manufactured from Boker in their Boker Plus line. This knife was originally called the Boker Kwaiken, and it was a flop. People were disappointed in how hard the knife was to open and they were disappointed because the tip of the blade peeked out of the handle when it was supposed to be closed. But Boker redesigned this knife in a flipper version. When the flipper version was first released, many collectors were after it to see if Boker had actually fixed the problems.

The blade on this knife is 3.5 inches long and made out of either AUS-8 steel or VG-10. The shape of the knife is a modified drop point silhouette that looks sleek and tucks into the handle perfectly. The tip on this knife is very fine, which makes it perfect for stabbing things. The AUS-8 steel is easy to sharpen. However, there were still many complaints about the steel because it isn’t the highest quality steel. That was when Boker released the upgraded version with the VG-10 steel. However, VG-10 steel is a little bit weaker than the AUS-8. Neither of the options hold their edge super well, but they both are durable enough.

The handle on this knife is unique. It sports full steel liners and has 3D machined pieces of titanium. Both of these materials are supports by a solid titanium back spacer. The handle was designed to have a minimalist look to it and is monochromatic. Some pros about the simple design is that it will work for almost any hand size. Some of the cons to the simple design is that there is really no texture to it, meaning the grip is lacking a little bit. The titanium keeps the knife sturdy and durable. However, because of all the titanium, this is a heavy knife. The handle features a pocket clip; it is a right side tip-up pocket clip. The flipper knife works because of the IKBS bearing pivot system, which helps flip well and open with a snap.

The overall length of the knife is 8 3/8 inches long and weighs 5.4 ounces. The blade thickness is 0.1 inches.


Pros of the Kwaiken Flipper:


  • The fine tip is ideal for piercing cuts
  • You can get the blade in either AUS-8 or VG-10 steel.
  • The steel is easy to sharpen.
  • The simple design helps to fit in any size hand.
  • Very sturdy knife.
  • Opens and flips well.





Boker has a rich history that slowly got them to where they needed to be. Today, there are five different Sub Brands that Boker USA owns, each of which specialize in their own categories. Boker Plus produces good quality knives, that aren’t quite as high quality as Boker, but they still are made with high quality materials so you know that you are getting a reliable knife. Boker Plus focuses on making tactical and outdoors knives. Today I chose two different Boker Plus knives to really focus on: The Plus Subcom and the Kwaiken Flipper.

The Subcom is a small knife that isn’t meant to do big tasks, but is great for having with you as a backup knife, a defensive knife, or for doing the smaller everyday tasks. The Subcom is great because there are so many different variations of it, so you really will get exactly what you are looking for. It’s a small knife, but it’s a good knife. The Subcom will be an old friend, not something you see every day, but will stand up for you when you need it to.

The Kwaiken Flipper has a history. The original Kwaiken was not an instant hit, in fact it was a disappointment. But Boker heard the complaints and re-designed it. It’s a sturdy, reliable knife, but it is a heavy knife. It will be able to stand up to the tasks that you throw at it.

These two knives are popular knives for a reason and it’s not a bad idea to try them out.
