Thug Heavyweight Balisong Butterfly Knife Review

The Blade:

The blade on this knife is made out of 440 stainless steel. In the 440 lien of steels, there are three different formulas: 440A, 440B, 440C. Out of these three, C is the best steel that you could get for your knife out of this series and A is the least quality. The tricky part about this is that often times the steel and knife manufacturer will only mark the tang of the blade with a “440” instead of including which formula it is. If this is the case, like it is for this knife, you can pretty accurately assume that you are getting either A or B, because C is a steel that most manufacturers are proud of. However, even if you are getting A, which is the least quality out of the three, it is an inexpensive and highly corrosion resistant stainless steel, so you don’t have to be disappointed in your blade. This steel was made in China, when a steel company developed the 440 lien to be a modified version of 7Cr17MoV by adding in more vanadium.  Unfortunately, this steel does not have high wear resistance, which means that it cannot stand up to heavy use or force. If you are choosing to use this steel for your day-to-day activities than this steel is going to help you get the job done. The two best qualities that this steel is going to boast is that it is inexpensive and it is very stain resistant, even in extreme environments such as salt water.

The blade has been finished with a black coating. The black coating is there to give this knife a very sleek look seeing as it is an all-black knife. However, the coating does serve a wider variety of purposes instead of just overall aesthetic. This is your typical powder coating, which is essentially a thick plastic coating that covers the blade. The biggest advantage to having a coated blade is that it helps to enhance the blades ability to resist corrosion. This is because the powder coat creates a thick layer in between the steel and the environment which means that as long as the coating is intact, nothing is going to be able to touch the steel. Secondly, the black coating reduces the shiny surface of the blade, which is a trait that people require on tactical knives. Thirdly, a coating can actually reduce a drag during a cut because it creates such an even surface. There are drawbacks to a coated finish, but the biggest issue is that a coating is going to chip, scratch, or peel off after heavy use or long term use. Once your coating does scratch off, the only solution to keep the qualities in check is to re-coat the blade.

The blade on this butterfly knife has been carved into a drop point style blade, which happens to be the most popular blade shape in the cutlery industry to date. This style of blade is popular for a reason: it is versatile and tough. Because of this, you can find a drop point blade on anything from hunting knife, to a tactical blade, to an everyday carry knife. The blade shape is formed by having the spine of the knife run straight from the handle to the tip of the knife in a slow, curving manner. The sharpened edge of the knife bulges out to provide the user with a large belly and then curves upwards to meet the lowered tip. The lowered tip allows you to control your cuts, allowing you to perform plenty of fine detail or tip work. The drop point blade also has one of the broadest tips that you are going to find throughout different blade styles. It is the broad tip that gives the drop point its characteristic strength that people have come to love and expect. Because it is lowered and strong, you are able to take on almost every day-to-day task as well as having the capability of using this knife for a tactical or even a survival knife if needed. One of the best features about a drop point style blade is that it has such a large belly, which allows the user to slice with ease. One of the most common things that you are going to perform with your knife is slicing, which makes this Thug a great everyday carry knife. The drop point blade does have one major disadvantage, which includes its broad tip. Because of the broadness behind it, you do lose out on almost all of your stabbing and piercing capabilities. If you are looking for an all-purpose knife that can also pierce, you should find a knife that boasts a clip point style blade.

This butterfly knife does sport a combo blade, which means that the upper half of the cutting edge (closer to the point) is a plain edge and the lower half of the cutting edge (closer to the handle) is serrated. This style of edge is designed to give you the best of both worlds. It is said that you can still slice and perform fine detail work with the half plain edge while being able to saw through thicker materials with the teeth of the serrated section. While in essence, this is a fantastic design, there is a complaint that because each of the portions is so small, you cannot actually use either portion well. This is a larger blade though, so this complaint should not come into play with this specific Thug knife.


The Handles:

The handles on this knife are made out of stainless steel. Stainless steel is not uncommon to find as a knife handle material, but because of the weight that it carries, it is also not a super common knife handle material. The benefits of stainless steel handles are that the steel does give the knife crazy high durability. A knife that has stainless steel handles is going to be a challenge to break. Because of this durability, this knife is going to be able to handle the wear and tear from everyday life with ease. In fact, it will even be able to take on a lot more than just your everyday wear and tear. One of the other advantages to the stainless steel handles is that it has very high resistance to corrosion. This makes it a challenge to rust which will cut down on maintenance time over the course of its life.

One of disadvantages is that stainless steel handles do not have a lot of grip to them naturally. To give the user a proper grip on this knife, the manufacturer does have to really work with the handles and add in grooves or ridges. On this knife, the manufacturer has skeletonized the handle to give the user a good grip. Going down each of the handles are five ovals cut out, each of these holes gets larger the closer they get to the butt of the handle.

The biggest disadvantage with having fully stainless steel handles is that stainless steel is going to be very heavy. This does weigh the knife down and this Thug knife is one of the heavier butterfly knives that you are probably going to use.

The handles of this knife flare out towards the butt to help give you a better grip on this knife. The handles have been coated with a black coating that matches the blade on this knife. The coating provides the same benefits that it did for the blade: it increases corrosion resistance, adds a nice color, and overall prolongs the life of the handle. However, it also has the same drawbacks that the coating on the blade did: the coating will scratch off after heavy use or long periods of time.


The Mechanism:

This all-black blade is a butterfly knife. This style of knife is also commonly known as a balisong knife, as well as a Batangas knife, and even a fan knife in some areas of the world. This type of knife is a folding pocket knife that has two handles instead of the usual one. These two handles counter-rotate around the tang (which is the portion where the handles attach to the blade) in a way that when this knife is closed, the blade is actually stored in the middle and in between each of the handles.

This specific butterfly knife is constructed in a sandwich construction, instead of the channel construction. The sandwich construction is where the knife is assembled in layers that are pinned together. This allows the pivot pins to be adjusted ore tightly without binding. And when the knife is closed, the blade rests between the layers. This contrasts the channel construction in which when the knife is closed, it would rest in a groove that has been created in the handles. The sandwich construction style is the more common construction; however, it is also the weaker of the two styles of construction.

The butterfly knife can be used for anything from shaving, to every-day purposes, to self-defense, and even as entertainment with manipulations called “flipping.”


The Specs:

The blade on this knife measures in at 4 inches long with handles that measure in at 5 inches long. When this butterfly knife is opened, it measures in at an overall length of 9 inches long. This is a heavier knife because of the stainless steel handles, weighing in at 7 ounces. This weight will allow you to take on tougher tasks, because you do have the heft that you need, but it will weigh you down. Overall, this is just a large knife.


The Pros of the Thug Heavyweight Butterfly Knife:

  • The blade steel is very stain and corrosion resistant.
  • The blade steel is inexpensive, which keeps the overall cost of the knife down.
  • The coated blade increases the corrosion resistance of the blade.
  • The coating on the blade cuts down and eliminates glares and reflections.
  • The coating adds a sleek look to the blade.
  • The drop point blade is strong, tough, and durable.
  • The drop point blade has an easily controlled tip.
  • The blade boasts a large belly that makes slicing a breeze.
  • You can perform detail work and slicing with the plain portion of the blade.
  • You can slice through thicker materials with the serrated portion.
  • This is a large knife, so you can take on tougher tasks.
  • The stainless steel handles are going to be strong and durable.
  • The stainless steel handles are crazy corrosion resistance.
  • Because the handle has also been coated, the life of this knife is going to be significantly prolonged.
  • The butterfly knife can be used for a wide variety of purposes.


The Cons of the Thug Heavyweight Butterfly Knife:

  • It is tricky to know which level of 440 steel you are getting with this blade.
  • The blade will not have high wear resistance.
  • The coating will scratch off eventually, because all coatings do.
  • Because of the broad tip, you won’t be super capable of piercing or stabbing with this knife.
  • Do you get enough of each edge style to really utilize them?
  • This is a very heavy knife, so it might weigh you down.
  • Because the handle has also been coated, once this knife reaches a certain point in its life, the coating will have worn off of both the handle and the blade and your knife will be extremely unprotected.
  • The sandwich construction is weaker than the channel construction.



The Thug Heavyweight butterfly knife is a fantastic choice for those just entering into the realm of butterfly “flipping” or if you want something that is as durable as it is cost effective. This knife boasts skeletonized stainless steel handles and a modified drop point style blade that is partly serrated and the integrated tang pin and pin construction is a true testament to why the Thug Heavyweight has been a top seller year after year.

The Blade:

This is a practice butterfly knife, which means that it sports dull edges. This blade has been made out of stainless steel. When it comes to the cutlery industry, there are really only two types of steels that a blade can be made out of, stainless steel or a high carbon steel. This can be confusing because stainless steel does contain carbon in its makeup. The biggest difference between stainless steel from regular or carbon steel is its chromium. Chromium is a metallic alloying element which has a silver color to it, resists rusting easily, and also resists corrosion easily. Because of this, stainless steel is known to standing up to rust and corrosion better than a carbon steel. However, stainless steel can still rust, so you just have to keep up on your maintenance, making sure that the steel is dry before you put the blade back into its handles. Of course, there are also disadvantages to a stainless steel. Stainless steel is less brittle than carbon steel, which means that it is more prone to deforming and also harder to sharpen. The upside to it not being brittle is that it is more chip resistant and will also retain and edge for longer period of time. In this knife, that actually doesn’t matter because there is not an edge that needs to stay sharp. When it comes to this knife, all you need to worry about is that this knife won’t chip but it may become a little disfigured. Stainless steels usually have at least 12% chromium. Stainless steel is technically tougher than a high carbon steel, but it is not going to be harder than a high carbon steel. Stainless steels also keep looking good for longer periods of time.

The blade on this knife has been finished with a satin finish. A satin finish is created by repeatedly sanding the blade in one direction with an increasing level of a fine abrasive, which most commonly a sandpaper. As a key, the finer the sandpaper and the more even the lines, the cleaner the finish will look. This finish is designed to show off the fine lines of the steel. This is the most popular finish in the cutlery industry, probably because of how classic of a finish it is. In terms of luster, the satin finish falls right in the middle. You are going to find finishes that are more reflective than this finish and you are also going to find finishes that are less reflective than a satin finish. With this in mind, you don’t have to worry about this trainer ever going out of style. The satin finish effectively cuts down on glares and reflections while also cutting down on corrosion.

Like earlier mentioned, this is a trainer knife, which means the edges are dull. However, it is roughly in the shape of a dagger style blade. To cut down on weight, because stainless steels are heavy, there are thirteen holes cut out of the blade. This also helps with drag, so it is easier to learn how to manipulate.


The Handles:

The handles are made out of stainless steel, just like the blade. Stainless steel provides excellent durability and resistance to corrosion, but it is not super lightweight. The durability factor is one of the most important factors when it comes to the steel and the blade. When you are first learning how to flip a butterfly knife, you are going to drop it and bang it around a lot. Without this durability level that you get from a stainless steel, the knife would not be able to last for as long as this knife is going to last. Also, stainless steel handles can be slippery, so manufacturers have to incorporate etchings or ridges to provide the required friction. In terms of this Gen Pro Trainer, there have been five holes cut down the length of each handle. These holes cut down on weight as well as give the knife better friction, so that you can have a solid grip on the handle. Another thing that helps with the user’s grip is that the handles are flared towards the butt. With a trainer, you need to have a very secure grip on your knife so that you can effectively learn how to manipulate a butterfly knife.

The handles on this trainer have been finished black. This adds a sleek look as well as increasing the corrosion resistance of the handles. Unfortunately, the black finish is going to scratch off eventually because it is not part of the stainless steel.


The Mechanism:

This is a trainer knife to learn how to use a butterfly knife, which means that it has been created just like a butterfly knife, except that it does not have a sharpened blade. Butterfly knives have a few different names, they have been called balisong knives, as well as a fan knife, and lastly a Batangas knife. The butterfly knife is a folding pocket knife, the difference between a butterfly knife and a regular pocket knife is that it has two handles that counter-rotate around the tang in a way that when closed, the blade is concealed within grooves in the handles.

The butterfly knife originated in the Philippines, so it was commonly used as a self-defense and pocket utility knife. Hollow-ground balisong were also used as straight razors before conventional razors were available in the Philippines. In the hands of a trained user, the knife blade can be brought to bear quickly using one hand. Manipulations, called flipping, are performed for art or amusement. Blunt versions of these knives, called trainers, are for sale to practice tricks without the risk of injury.

While a regular butterfly knife is now illegal in many countries, often under the same laws and for the same reasons that automatic knives are, trainers are usually legal anywhere. Of course, you should know your local knife laws.

There are two styles of construction when it comes to butterfly knives. There is sandwich or channel. This knife has been constructed sandwich style. Sandwich constructed balisong knives are assembled in layers that are generally pinned or screwed together. They allow the pivot pins to be adjusted more tightly without binding. When the knife is closed, the blade rests between the layers. This style of construction is the more popular style of construction, but it is also the weaker style of construction.

There are a few parts to a butterfly knife that are unique specifically to butterfly knives. The first piece is a bite handle, which is the handle that closes on the sharp edge of the blade. This handle will cut the user if they are holding it when the they go to close it. But because this is a trainer, you don’t have to worry about that. The bit handle is also the handle that has the latch on it. The other handle is known as the safe handle, which is the handle that closes on the non-sharpened edge of the blade.

The next piece that is specific to a butterfly knife is the latch. This is the standard locking system, which holds the knife closed. The latch is also what keeps it from opening up when the user doesn’t want it to. There are a few styles of latches. The first is the batangas, which is the latch that is attached to the bite handle. Another style of latch is a manila, which is when the latch is attached to the safe handle.

Along with the latch, there is a tach gate, which is a block inside the channel of the handles stopping the latch from impacting the blade.

The next few pieces that are specific to a butterfly knife is the tang pin, which is the pin meant to hold the blade away from the handle when closed to prevent dulling.


How to Flip:

To perform a basic flip there are a few steps. The first step is to hold the knife from the safe side, which is the side where the sharpened edge would not close. This step is not as important with a trainer, because there is no sharpened side, but once you move to a real butterfly knife, don’t forget about this step.

The second step is to flick your wrist back. Hold the knife directly out in front of you, pointing forward. Now flick your wrist back. The flick of your wrist should be similar to the reverse motion of casting a fishing line. When you flip your wrist back, the knife will open and the handle of the sharpened side with hit you between your thumb and your forefinger. At this point, you should keep your hand where it is.

The third step is to flip the knife back forward. This time, flick your wrist downward so that the knife closes again. The knife should be a similar positon to when you started now.

The fourth step is to open your thumb and flip the knife up again. The last time you flipped the knife up, the handle hit you on the thumb and forefinger. Flip the knife up in the exact same way, but open your thumb and move it to the side this time. This will allow the handle of the sharpened side to smack into the handle that you are holding, engaging the knife. Once you have flipped the knife up into place, close your thumb over both handles.

At this point, you will have performed a basic flip. Of course, this is just one type of the basic flip and you can get more complicated as you go further and become more adept at flipping.


The Specs:

When this trainer is closed, it measures in at 4 7/8 inches long. The overall length of this knife measures in at 8 7/8 inches long.


The Pros of the Gen Pro Trainer Butterfly Knife:

  • Stainless steel resists rust and corrosion easily.
  • Stainless steel also looks better than a high carbon steel for a longer period of time.

  • This knife is constructed just like an actual butterfly knife, including the size of this knife, so you can get down the flipping mechanism and not feel out of your league when you do move on to an actual butterfly knife.


The Cons of the Gen Pro Trainer Butterfly Knife:

  • The stainless steel may become disfigured.
  • The stainless steel handles are going to be heavy.
