Pro-Tech Strider PT Automatic Knife

Pro-Tech Knives, LLC is a knife company that has been around since 1999. They are a family owned company who designs and produces high quality American Made knives. Pro-Tech strives to use only the finest materials that are available and use the newest high tech manufacturing processes. Because of this, you know that your knife is innovative, modern, and will last you a lifetime. To keep quality of their knives high and customer satisfaction higher, they manufacture their knives in small batches, around 12,000 each year. By keeping their batches smaller, they can take the time to hand fit and finish each individual knife, creating a level of quality that is hard to come by on factory made knives.

Pro-Tech has collaborated with high end knife makers and have also produced knives for the U.S. Military and a couple of police departments. Some of their most well-known knives are the Runt J4 and the Godson. Pro-Tech recently came out with a brand new knife that I’m sure will be just as big of a hit. They named this new knife the Dark Blue Strider.


The Blade:

ProTech PT Strider Auto Knife
ProTech PT Strider Auto Knife

The blade on this knife is made out of the high end stainless steel 154CM. This steel is made by Crucible, who produces ground breaking and high quality steels. To create this type of steel, Crucible took the regular 440C steel and added Molybdenum. This extra Molybdenum helps the steel have fantastic edge retention and great levels of corrosion resistance. This steel is relatively easy to sharpen, when you have the correct equipment. This steel is tough enough to get the job done. 154 CM stainless steel has many similar qualities to S30V, although slightly inferior, for a much more inexpensive cost. You have a couple of options when it comes to the knife finishes. There is a black finish, a stonewash finish, or a bead blasted finish. The bead blasted finish is created by shooting small ceramic or glass beads at the blade with a high pressure system. This creates a more matte finish, reducing reflections and glares. However, it does create micro abrasions in the surface, so your blade will be more prone to rusting or corroding. This finish gives you a gray look to it. The stonewash finish is created by tumbling the blade around with pebbles. This finish easily hides scratches and reduces glares and reflections. This finish is the most silver out of all of them.

The shape of this blade is the versatile drop point blade. This shape of blade is perfect for an everyday, all-purpose knife. This is a durable shape that can really stand up to any task. This shape of blade gets its name because the unsharpened edge of the blade runs from the handle to the tip in a slow curve. Because of this curve, it creates a lowered, or dropped, point. There are a handful of advantages to having the tip on your knife lowered, one of them being that you will have more control over your blade with a lowered tip. Hunters especially love the drop point shape because it allows them to do precision work without piercing the organs while they are skinning their game. Another one of the advantages to having the tip of your blade lowered is that it adds strength to the tip. The tip is on the broader side of things, especially compared to a clip point, but because of the broadness, it is much more durable than that of a clip point. Because of the strength behind the point, this shape is great for tactical and survival knives. One of the characteristics of the drop point blade shape that makes it so versatile is that it sports a large belly area. This belly allows your blade to excel at slicing. With all of the benefits of a drop point blade, it can seem like there are no disadvantages to it. This is almost true, except for with a broad tip, this blade is not going to be able to pierce or stab as well as a clip point would. This shape of knife is great for every situation, whether it is the expected or unexpected.

This knife has two options for the edge. The stonewash and bead blasted versions are both plain edged. Plain edged blades are going to be easier to sharpen, because they do not have the teeth that a serrated edge does. The plain edge excels at shaving, peeling, and skinning. When people prefer a serrated blade, it is usually because serrations can cut through harder and tougher materials. However, when a plain edge blade is sharp enough, it can also cut through those hard and tough materials. There are two options for the black finish: a plain edge and a combo edge. The combo edge is popular because it gives you the best of both worlds; you get the plain edge for the easier tasks and the serrated portion for the trickier tasks that are presented to you.

On the unsharpened edge of the blade, near the handle, there is a series of thick jimping. Jimping is the notches down the spine of the blade that help to provide grip on your knife.


The Handle:

The handle on the Pro-Tech Strider is made out of T6-6061 aluminum. Aluminum is a very durable material. One of the biggest advantages about aluminum is that it provides you with the hefty feel that many knife lovers long for, without actually weighing you down. This is because aluminum is a low density metal that is very lightweight. This version of aluminum, the T6-6061 allow, has incredible strength behind it. This allow is also the most common type of aluminum used today. Aluminum is very strong and very resistant to corrosion. There are a few drawbacks to aluminum though. One, aluminum is a cold material. If you work in a cold environment or live in an area that experiences winter, this knife is going to bite into your hand. Another drawback is that aluminum is a slicker material. Pro-Tech, to avoid having no grip on the handle, has added jimping in a few places. It also has a deep finger groove to provide you with extra grip. The last drawback to aluminum is that it is prone to scratches and dings. To combat the accumulation of scratches on the Dark Blue Strider, Pro-Tech has anodized the aluminum. There are many benefits to the anodization process. This process adds strength and durability to the knife. The most obvious benefit of this process though is that it adds color to the aluminum. Pro-Tech has anodized the Strider to a dark blue.

One of the most defining aspects about the Strider’s handle is the shape of it. The handle has a slow, triangular shape to it, wider at the butt than it is at the top. The butt of this handle has an angled portion with jimping on it. This slightly flared butt will provide you will better grip and better control over your knife.


The Pocket Clip and Hardware:

Both the pocket clip and all of the hardware on the Dark Blue Strider is black, matching the black versions of the blade and contrasting with the stonewashed blade. This pocket clip is sturdy. The pocket clip can carry your knife tip up and only on the traditional side of the handle. With the black hardware and black blade, this knife has an elegantly modern look to it. The only exception to the black hardware is the bead blasted version of the Dark Blue Strider. This version has gray hardware to match the blade.


The Mechanism:

The Dark Blue Strider is an automatic, or switchblade, knife. Like always, automatic knives have pretty strict laws behind them that vary depending on where you live. Make sure you know your local knife laws before purchasing this knife and especially before carrying or using this knife. A switchblade knife works by pressing a button to automatically open the blade. There is a spring encompassed in the handle of the blade that has significant pressure on it when it is in the closed position. When the button is pressed on the Strider, the spring is released, popping the blade out of the handle. A black thumb stud on the blade stops the blade when it opens all the way. The blade is locked into place. When you want to close this knife, you press the button again, which unlocks it, and push the blade back into the closed position.


The Specs:

The overall length of the Dark Blue Strider is 6.4 inches; this knife is on the smaller end of the spectrum. The closed length of this knife is 3.65 inches long, which will fit comfortably, securely, and well concealed in your pocket because of the small size. The blade length on this knife is 2.75 inches long, big enough to get the job done, but again, everything about the Strider is big things in small packages. This knife weighs 2.5 ounces.


Pros of the Dark Blue Strider:

  • The steel of the blade has great edge retention and corrosion resistant properties.
  • The steel offers only slightly inferior qualities to S30V, but for a much lower price tag.
  • The steel is easy to sharpen.
  • The steel is tough enough to get the job done.
  • The drop point blade shape is the most versatile out of the blade shapes.
  • The lowered point gives the user better control and extra strength.
  • The belly on the drop point blade shape gives you plenty of room to slice.
  • The plain edge is easy sharpen and excels at shaving, peeing, and skinning.
  • The combo edge allows you to cut the thicker and tougher materials.
  • You have the option of three different finishes, all with their own pros and cons.
  • Pro-Tech has added jimping to the blade to give the user better grip and control.
  • The aluminum handle is strong and tough.
  • The aluminum has been anodized to add a dark blue color.
  • The aluminum is lightweight, but still provides you with a hefty feel behind it.
  • Aluminum is very resistant to corrosion.
  • The slightly flared handle gives the user more control over their cuts.
  • The pocket clip and hardware are black to match the blade; giving you a very aesthetically pleasing look.
  • The automatic mechanism will open quickly and efficiently.


Cons of the Dark Blue Strider:

  • The pocket clip has only been fitted for traditional carry, so it is not ambidextrous friendly.
  • The pocket clip only allows the knife to be carried tip up.



Pro-Tech has released many knives that are huge hits in the knife communities. This company chooses to keep their knife batches low so that they can give each individual knife the attention that it deserves. Pro-Tech hand fits and finishes every single knife to provide the user with a quality that is hard to find in factory made knives.

The Dark Blue Strider is the newest of their masterpieces. They started with a tough steel to get the job done and gave the user three different options for the finishes. The blade shape is the most versatile of them all: the beloved drop point. The user also has the option to decide between getting a plain or combo edged blade. The handle as a unique shape to it, giving you the most control. The durable aluminum handle has a modern dark blue color to it. With the Pro-Tech Dark Blue Strider, they gave you a perfect auto knife in a small package. You are not going to want to put this knife down.


ProTech Dark Angel OTF Knife Review

The Pro-Tech Dark Angel OTF Knife


ProTech Dark Angel
ProTech Dark Angel OTF Knife

Pro-Tech is a family owned company based out of Sante Fe Springs California. Pro-Tech has made its name by producing fantastic automatic knives. They have been building these high quality knives for over 17 years now. This company was founded by Dave Wattenberg in 2001. Since then they have collaborated with knife makers such as Ernest Emerson, Walter Brend, and Allen Elishewitz. Some of the most famous and most popular knives that Pro-Tech has made have been the Godfather, Godson, and the Runt J4.

The company’s mission is to produce high quality knives made out of the finest materials that they can get ahold of. Pro-Tech makes smaller batches of knives than most companies so that they can hand fit and finish each knife to produce higher quality knives than you could find if it was factory made. Because of these smaller batches, they make around 12,000 knives a year.

The fantastic knife that Pro-Tech has developed that we are going to discuss today is the Pro-Tech Dark Angel Out-The-Front knife.


The Blade:

The blade on this knife is made out of 154CM steel. 154CM is a high end stainless steel that has been made by Crucible. This is a relatively hard steel. 154CM steel is considered to be an upgrade from 440C steel, because 154CM steel has Molybdenum is added. Because of the added Molybdenum, this type of steel can hold a fantastic edge while it also holds on to its corrosion resistance properties. However, even though this type of steel is a stainless steel, it will rust if it is left in wet or damp environments. To prevent this happening to your knife blade, especially if you live in a humid environment, you should always remember to keep your blade clean and oil it often. You shouldn’t be turned off from this steel just because it might rust—any stainless steel will rust if left in damp environments and neglected. You just need a little extra maintenance with 154CM stainless steel. This steel is also fairly easy to sharpen.  This steel type has pretty good toughness; it has high enough levels of toughness to stand up to most tasks—including the heavier duty tasks that you will throw at this blade. This steel is found commonly in quality pocket knives. In fact, Emerson Knife Company uses this type of steel exclusively. This type of steel maintains lots of good, durable properties, but it is less expensive than a premium steel such as S30V. This steel has a good balance between being hard, tough, and resistant to corrosion. This specific knife design comes in a variety of different blade colors, some being: black, silver, and even a custom Damascus blade. All of these knives have plain edges.

The shape of this blade is a dagger style. This style of knife has also been known as a needle point blade. This shape of blade is a double-edge blade designed to be able to thrust and stab. The blade comes to a very thin, sharp point, providing you with maximum ability to pierce into your target. However, because it has such a fine point, the tip is more prone to breaking, especially if you are stabbing a hard target. The double edge means that instead of a normal knife only being sharpened on one edge and having the back, or spine, unsharpened; this blade does not have an unsharpened side. Both edges on this blade have been sharpened. Because it is able to cut on both sides, this blade shape is a fantastic option for a self-defense weapon. Especially if you are in tight quarters. One disadvantage to having a dagger style blade is that it has no belly and the edges get thick quicker than most styles of knives. These two characteristics make it a poor choice if you want to slice anything. In the center of this blade, there is a thin cut out. This cut out cuts down on weight that the blade would have had otherwise. This blade cut out also offers a unique look that you won’t find on many knives.


The Handle:

The handle on this knife is made out of 6061T6 hard anodized aluminum. A hard anodized aluminum creates an oxidation layer on the aluminum that can make your handle up to 30% harder than some stainless steels. When an aluminum is anodized, it provides the aluminum with color. This knife comes in a variety of different colors. Some of your options are silver—with two finishes: satin and stonewash, black, desert sand, or dark desert sand. Anodizing the aluminum also offers extra harness and protection. This is the most common form of finishing aluminum and it makes your aluminum handle very durable. Because aluminum has such a low density for a metal, it offers you a heftier feel without the added weight. Aluminum can be slippery, especially in wet environments, unless properly texturized. When it is properly texturized, your grip on it will be reasonable, but still not fantastic. Another drawback to having an aluminum handle is that it is going to feel so cold in a cold environment and can start to feel very uncomfortable in your hand. Other than feeling cold, aluminum is a comfortable material that is easy to use, even for long periods of time. Aluminum is very resistant to corrosion. However, it can be easy to scratch the surface or ding it up a bit. The handle will still work perfectly after this, but it won’t look as aesthetically pleasing. If you are going for a truly superb handle material, you might want to check out aluminums brother, titanium.


The Pocket Clip:

The pocket clip on this knife is newly designed from Pro-Tech. This is a customized part of this knife. This clip actually folds over itself helping allow a deep “hidden” in the pocket look. The benefit of a deep carry pocket clip is that it is not going to slip out of your pocket. With a deep carry clip, you know that your knife is safe and secure in your pocket. This specific pocket clip allows you to conceal your knife better than other pocket clips.


The Mechanism:

The Pro-Tech Dark Angel is an automatic out-the-front knife. Like always, automatic knives are not legal in all states or areas. Before you purchase and/or carry this knife, make sure you know your local knife carrying laws. An out the front knife is a unique style of automatic knife. Instead of the blade folding or flipping out of the side of the handle, there is a hole in one end of the handle where the blade pops out of. The blade of an OTF knife travels on an internal channel, at the bottom of this channel, there is a spring that launches the blade out, when the button or trigger is pushed. This is only a single action OTF automatic knife. This means that to deploy the knife, you push the button and the blade will pop out, but to put the blade back in, it takes a little more work. To close this knife, you push the button down and at the same time, you slide the charging bar back along the side. Because there is more of a mechanism that has to lay inside of an automatic OTF knife, the handle has to be thicker or longer than a manual OTF knife.


The Sheath:

This knife comes with a nylon sheath. Nylon is a very common material used for knife sheaths. This is a relatively inexpensive material, especially compared to kydex or leather sheaths. However, you do get what you pay for. And while nylon is a cheaper material, it will be more prone to wearing out quicker than these two previous materials. Nylon also has the tendency to stretch out over time, and while the sheath will still work adequately at that point, your knife won’t be held as securely or snugly. However, I shouldn’t be focusing on the negative. There are many fantastic characteristics that nylon sheaths have. For starters, nylon is resistant to rot and mildew. They are not as vulnerable to water as a leather sheath would be. This means that your sheath will need a lot less maintenance than other sheath materials would need. Plus, nylon is not easily scuffed or torn. Another big bonus about nylon sheaths is that the nylon is relatively quiet. If you are trying to be stealthy or conceal yourself, nylon won’t give you away. Nylon is not as silent as leather would be, but it’s not loud, especially when compared to a plastic or kydex sheath. This nylon sheath will get the job done for you and last quite a while.


The Specs:

The Pro-Tech Dark Angel’s blade is 3.75 inches long with a blade thickness of .125 inches. When this knife is open, it measures at 8.9 inches long. When this knife is closed, it measures up at 4.5 inches long. This knife weighs in at 3.4 ounces. This size and weight are the perfect size and weight for an everyday carry knife.


Pros of the Pro-Tech Dark Angel:

  • The steel is a high end stainless steel.
  • Holds a fantastic edge and is still easy to sharpen.
  • The blade has high corrosion resistance abilities.
  • The blade has high toughness that can take on even the heavier tasks.
  • This steel has good properties and is still cheaper than S30V or other premium knives.
  • The blade comes in multiple different colors.
  • Has a very fine tip, perfect for stabbing.
  • Both edges are sharpened, so it is a perfect weapon for self-defense.
  • Anodized to add color, hardness, and protection.
  • Aluminum handle is durable, but not with the added weight.
  • Aluminum is very corrosion resistant.
  • Aluminum is a very comfortable material to hold.
  • Pocket clip is custom, deep carry.
  • Automatic knife, so it will deploy very quickly.
  • Included nylon sheath has many fantastic properties for a lower cost.


Cons of the Pro-Tech Dark Angel:

  • The dagger style has a fine point; it is prone to breaking if used incorrectly.
  • Aluminum handles will feel extremely cold in cold environments.
  • Aluminum can be very slippery, especially when not texturized properly.
  • Automatic knives are not legal in all states or areas, so you have to be careful when purchasing and carrying this knife.
  • Nylon sheaths will not last forever; they will break down eventually.



Pro-Tech is a unique company. They have a hybrid of mass producing knives and building each one custom. They make their knives in small batches, only around 12,000 knives a year. They keep them small so that they have the ability to hand finish each and every knife. They use the highest quality materials to produce the highest quality knives that you can stumble across. Each one has taken time, and care, and they are truly remarkable. Pro-Tech has been around for over 17 years and they have been producing fantastic knives ever since. They have collaborated with knife makers such as Ernest Emerson and Walter Brend. Pro-Tech knows what they are doing when they design, build, and finish all of their knives.

The Dark Angel has been no exception. They started out with a high quality steel that can take on almost any task that you throw at it. This steel can get a fine point and they enhanced this by giving the blade a dagger style shape to it. By giving the knife this shape, they have created an excellent self-defense weapon. They designed a custom pocket clip to top the whole automatic knife off. And with this fantastic knife comes a great nylon sheath. This is a remarkable knife that has been exceptionally produced. The Pro-Tech Dark Angel would be a fantastic addition to your knife collection and it would make a perfect everyday carry knife for you.

ProTech TR-5 Tactical Response 5 Assist Knife Review

TR-5: Tactical Response 5

The Tactical Response 5 is Pro-Tech’s first Spring Assist knife. You wouldn’t know that with how quick the knife launches out. This spring assisted knife has the power and speed of an automatic knife. As of January 2016, it is the newest of the Tactical Response folder family which features the new Titanium Assist mechanism designed by Matthew Lerch. The TR-5 is a smaller version of the popular Tactical Response TR-4.

The TR-5 Story
Pro-Tech is a family owned company. Established in 1999, they have been creating and developing high-quality knives that are made here in the United States. Recently I inquired of Pro-Tech’s President, Dave Wattenberg, about the new Tactical Response. This is what Dave had to say,

“A few years ago I was chatting with my good friend and custom knife maker Matthew Lerch at the blade show—he had an idea for a spring assist mechanism that would combine the ‘snap—and quick action’ of our cool spring with a spring assist mechanism. After a few years of tinkering – we were able to engineer the mechanism into this new smaller version of the TR-4 (the new TR-5).”

Rumor also has it that following this conversation, the idea for this new spring assist mechanism was developed in a matter of minutes where many ideas take a greater amount of time to come up with. Whether or not this is true, we have this amazing knife with us today to enjoy.

Matthew Lerch
Matthew Lerch is the mastermind behind the new Tactical Response TR-5. He was initially trained in the watchmaking industry and as a jeweler but later moved into manufacturing and tool making. Aside from the mechanics of the TR-5, Matthew has a few patents under his name for knife mechanisms such as the Fire Safe. He has also been honored with some prestigious awards, including the Buster Warenski award. Matthew views knives and knife making as something more than a tool and a process. He sees them as functional pieces of art. Of Matthew Lerch, Dave Wattenberg, said about him, “Matt Lerch is really one of my favorite knife makers—he’s a mechanical genius.”

Below is an overview of the different specifications of the Tactical Response 5. Many of the things listed will be covered later on, but here is a simple glance at what the TR-5 has to offer.

  • Product Type: Spring Assist
  • Overall Length: 7.66″
  • Weight: 3.5 oz.
  • Handle Length: 4.36”
  • Blade Length: 3.30″
  • Blade Thickness: 0.125″
  • Blade Material: 154-CM
  • Blade Edge: Plain
  • Blade Style: Drop Point
  • Blade Finish: Stonewash
  • Handle Material: Anodized 6061-T6 Aluminum
  • Handle Color: Black
  • Pocket Clip: Tip-Up
  • Glass Breaker and Lanyard Hole Included
  • Made in the USA

One thing that can be pointed out here is the handle. At a first glance, it doesn’t look too special. But at a closer examination of it proves otherwise. The black anodized aluminum handle is smooth to the touch and feels great when holding it. When deployed, the knife has comfortable finger gripping that serves for an easier hold, as was as a more secure hold. The handle is accented with a glass breaker and lanyard hole to give flair to the rest of the knife. The overall look of the knife looks great and pleases the aesthetic eye.

Out with the Old, In with the New

The Tactical Response 5 is the newest knife in the Tactical Response Series. It is an alternative to the older Tactical Response models. It is smaller in every way but still performs just as well.

TR-5 TR-4 TR-3
Overall Length 7.66″ 9.25″ 8.00″
Blade Length 3.30″ 4.00″ 3.50″
Handle Length 4.36″ 5.25″ 4.50″
Weight 3.5 oz. 5.4 oz. 3.6 oz.
Product Type Spring Assist Auto Auto
Steel 154-CM CPM-D2 154-CM

All of the knives in the Tactical Response line are phenomenal knives. Each has their own unique properties to them. They are all quick and sharp right out of the box. The TR-5 allows more people to carry Pro-Tech with the same speed as an auto but still be classified as a spring assisted knife.

New Mechanics
The Tactical Response 5 features new mechanics that make allow the assisted folder to compete with automatic knives. It is difficult to even begin describing how this thing works. It is absolutely flawless. Here is my best shot. Most, if not all spring assisted knives to have either a thumb stud, or a thumb hole, or some other device that a thumb can move which allows the blade to partly open before a spring takes over and launches it into its “on” position. Other spring assisted knives may include a flipper on the back of the handle that will flip the blade open. A typical spring assist knife has a variety of mechanisms that make the knife work. They more or less have a common theme among them all. A normal spring assist knife has a spring or tension bar that acts as the main part that moves everything else around. There is tension all around inside these knives. They help flip the knife open, but they also help keep the knife closed. Thus, there needs to be some sort of manual force to overcome the resistance the spring gives off to open the knife.

The new mechanics that are featured in the TR-5 are unique and different in many different ways. The first major difference is that the Tactical Response 5 does not have a traditional spring or tension bar. The TR-5 utilizes Pro-Tech’s high-quality springs that are found in their snappy automatic knives. And rather than having a typical tension bar that runs the length of the handle, there is a bar that is in the shape of a half circle on both sides of the handle, on the inside, that is connected by a metal peg. This half circle bar functions similar to your standard spring bar. It provides the same amount of pressure when opening and closing the blade. It is difficult to describe how it all works, but the most important thing to know is that this knife is sweet. The new mechanics make it quick, if not faster than many automatic knives in the industry.

In that inquiry with Dave, he was able to help me out in describing how the knife operates. This is what he had to say,

“The mechanism he (Matthew Lerch) invented is really very simple and one of the really strong points is that there are only a few parts.

“The parts, however, have to be extremely precise. Two wire EDM (Electrical Discharge Machine) cut titanium springs are installed on the inside of the frame—they hold a dowel pin across the inside of the handle, there’s a notch in the blade that this pin locks into. Since our coil spring is strong it takes a strong detent to keep it closed in the locked position.

“As you open the knife with the thumb stud, at the moment you push past where the pin locks into the blade our Superior Coil Spring Action takes over! And of course, our proven button lock works to lock the blade into the open position.

“Since there are only a few (albeit very precision) parts—the mechanism is very sturdy, even more so than some spring assist mechanisms on the market.”

Hopefully between both of our descriptions, the mechanics of the knife works make more sense. The bottom line is that the TR-5 is quick, it is dependable, and it is awesome.


The steel used in making the drop point blade on the TR-5 is the sturdy 154CM. 154CM is a favorable steel when it comes to knives. It is a high-end stainless steel made in America by Crucible Industries. It is a newer stainless steel that is just as good as or better than 440c stainless steel. The Rockwell test for this steel is around HRC 58-61. 154CM is popular in survival and tactical knives because of its corrosion resistance. It may be exposed to salt water and other corrosive material for long periods of time. This steel is comparatively cheaper than other high-quality steels such as BG-42 and S30V. Having this steel on any knife, especially the TR-5, makes it an even better knife.

Blade Finish

A stonewash finish is fairly new in the knife community. The process begins when a blade is rolled and tumbled with pebbles and an acid of sorts, then smoothed. In theory, it can hide scratches or other abrasions to the blade. This is a favorable characteristic that many knife owners desire. Because of the tumbling process to create this finish, it looks as if there are already hundreds of markings on it. Yet, the markings are done in a natural way to form a work of art. Similar to a snowflake, no two stonewashes are the same. The finish has a different look to it. The stonewash finish on the Tactical Response 5 almost has a satin finish to it. Direct light reflects off the blade. Because of the style of the finish, there need not be any concern about scratches or other markings to the blade. The knife can be used for its intended purpose of cutting and doing any other type of work. Some suggest that because of the process, a stonewashed knife can become more resistant to rust as well. The acid oxidation it goes through in the process enhances a blade’s rust resistance with a stable oxide barrier between the steel and its surrounding. Another benefit of stonewashing a blade is their low maintenance and their ability to preserve their original look over time.

Tactical or Every day Carry

“The size, shape, mechanism of the TR-5 spring assist really make it a perfect knife for every day carry. I started carrying one myself in January and just can’t seem to swap it out for any other knife from my pocket!” –Dave Wattenberg

The Tactical Response is a highly functional knife. It works great as either an everyday carry knife or as a tactical knife. For some, a tactical knife and an everyday carry is the same thing. Either way, there are several key characteristics to consider before purchasing a knife. The designed purpose, the ergonomics of the knife and its size, the materials used to make the knife, and the blade design and style, are all factors in choosing a great knife.

Designed Purpose:

Some knives are created for those in the armed forces to help them out with their problems they encounter while other knives are created for a more day to day type of carry that can be of use in self-defense or other menial tasks. As the name of the knife suggests, the TR-5 is a tactical response to the need for a decent knife in the industry.

Ergonomics and Size:

A knife that is built with the highest quality of material would be utterly useless if it does not feel right when holding it. When a knife feels secure in your hand, you can feel secure as well. The TR-5’s size is great for an everyday carry or a tactical knife. It is small enough to carry, yet big enough to do some damage.


Any knife, no matter its purpose, is going to be going through a major beating. Because of this, it needs to be built out of a strong, high-quality material. This includes both the blade steel and the handle material. The handle on the Tactical Response is made of an aluminum alloy. This is perfect for the knife to help it be lightweight and durable at the same time. And of course, the steel is made of a high-quality material.

Blade Design and Style:

The blade for a tactical or an everyday carry should be an all-around useful tool to tackle all sorts of tasks. The blade can make or break any knife. A good versatile blade is a drop point. And that’s just what the TR-5 has equipped on it. With this blade, the TR-5 is useful for any number of tasks.


“I’m very pleased to produce a knife with my friend Matt Lerch’s design and very proud of the product that it’s become.” These were some of the closing remarks that Dave had with me when discussing this knife. Truly, this knife is remarkable. It shares the best of both worlds when it comes to automatic knives and spring assisted knives. Along with Dave, I would highly recommend picking up the Tactical Response 5. You will not be disappointed with it. The TR-5 awaits your response.

ProTech Desert Sand Tactical Response Auto Knife

ProTech Tactical Response 3.31
ProTech Tactical Response 3.31

The ProTech TR3.31 boasts the new desert sand anodized handle that ProTech has been producing over the past few years.  I picked up one of these ProTech knives with a tanto point about two years ago with the Desert Sand anodize finish.  At the time, it was a limited run offering.

Since then, I have carried the knife for about 150 days of hard, daily use.  It has performed beyond my high expectations.  I have purchased several ProTech knives over the past decade and have been impressed by each one–so my expectations were high.  The anodized handle is comfortable to hold even for long periods of use.

The drop point blade snaps open fast with classic ProTech speed and quality.  The blade is 154CM stainless steel with a black finish.  It is built for heavy use and will last a lifetime with proper care and maintenance.

If you are looking for a high quality auto knife that will perform exactly how a knife should–check out this fine offering from ProTech Knives.

ProTech Tactical Response 3 Auto Knife

If you haven’t had the chance to hold a ProTech Tactical Response knife, find a way to make it happen.  This knife design continues to be one of the most popular ProTech knives on our shelves for one specific reason–it is spectacular.

You can find a TR3 with various handle inlays, or you can pick it up with just a basic, no nonsense anodized aluminum layout with no inlay.  The handle is 4.5″ long and the most prominent feature is the finger groove that makes it, in my mind, such an excellent knife.  The finger groove is a 1 1/8″ long and about 3/8″ deep in the middle.  The smooth, gentle curve of the finger groove allows your forefinger to sit comfortable.  It also indexes the rest of your hand so that your grip is solid and secure.  Your thumb naturally sits on the spine where some wide jimping and a very shallow depression sit that allow your thumb to control the blade with confidence.  There is additional jimping on both the top and bottom edge close to the butt of the handle.  Across the face of the non-inlaid model, run four channels that give the knife visual texture and even more grip points.  All told, one reason this knife is so great is because the handle gives your hand a solid, secure grip while allowing you full blade control.

The blade is 154CM stainless steel and is available in various finishes and even with a combo edge in some of the variations.  A classic clip point style blade, it excels at slicing tasks.  The blade snaps out extremely fast–just like every ProTech auto.  Push the inset button and the blade is ready for action.  Lock up is tight.

The knife has a tip up, removable pocket clip.  You can find the ProTech Tactical Response knives here on our website.  Let me know what you think of yours down below.

ProTech Sprint Automatic Knife — Snapshot Review

Blue ProTech Sprint
Blue ProTech Sprint automatic knife

The ProTech Sprint auto knife has been delighting users for several years now.  Built with a Cali-Legal sized 1.94″ blade, the push button auto snaps open with serious authority. There are several things about the Sprint series that make the knife absolutely fantastic.  First, the 6061 T6 aluminum handle frame is thin.  By thin, I mean amazingly thin.  It measures just 3/8″ thick which makes it one of the slimmest auto knives you can find on the market.  Second, because it is a ProTech, it is built with some serious attention to detail.  The seams, edges and finish of this knife is extraordinary.  Third, the Sprint is fantastic because it gives you a knife blade you can depend on for serious every day cutting.  This will do more than just open your mail and the occasional package.  This knife is built tough enough to cut nearly whatever you need to cut.

ProTech Runt J4 Knife Review — Video Review

For the record, I’m biased.  I have a ProTech Runt J4 and it is one of my all time favorite small automatic knives.  And just so you can see how excellent it is, here is a quick video review for your viewing pleasure:

Black and Grey Jazz Knives from ProTech

Just released from ProTech are several of their knives with unique Black and Grey Jazz anodized aluminum handles.  I really like the look of these knives.  Here is a picture of the Doru 2019 with the special handles.
