It has its origins in Filipino martial arts and is designed for quick handling and opening. When opened, this type of pocket knife resembles a small knife. When closed, the two halves of the handle form a cover for the blade. In this article, you will learn about the best butterfly pocket knife models and also what you need to consider when choosing yours.


  • The butterfly pocket knife is designed to have an easy and agile opening of its blade. It is because of this ease that it becomes exciting and its use becomes a real art, with so-called flippings.
  • The blade of this type of pocket knife is sharp and is used to cut only on one side. The other side of the blade does not offer any cutting risk.

What is the butterfly pocket knife and what are its advantages and disadvantages?

The butterfly pocket knife is a pocket knife, created in the Philippines and used in martial arts in that country. This object has two handles, which can rotate counterclockwise. When they meet at the base, they form a single handle, and hide the blade. This type of knife is used to perform the so-called “flipping” movements, which are the manoeuvres performed with a butterfly. Its sale is prohibited in some countries. In Brazil, however, it is allowed to have a pocketknife at home. Injury with a penknife, however, is considered a white weapon crime, as you will see below. Check out a list with the advantages and disadvantages of having a butterfly knife at home.

What do you need to pay attention to before buying a butterfly knife?

The first thing to look out for is whether the butterfly knife has a corded or cordless blade. If you are a beginner, it is recommended to try your first flippings the butterfly knife without a blade to avoid accidents. After all, you learn by making mistakes, and you don’t need to cut yourself to learn. Probably the most important part of the butterfly knife is its blade. It is important to check the type of material used. There are types that rust more easily than others. In addition to resisting corrosion, the blade needs to be resistant. In extreme cases the blade can break, if the material used is not hard enough. To understand how to choose the right blade, keep reading to understand the acronyms used to describe the type of material. The second fundamental point is the opening mechanism. There are two types: screw and rivet. We explain in the following section more details on both options.

What is the legislation regarding this pocket-knife?

Before making a purchase, it is worth checking where and when you can use the butterfly knife. Think about where you are likely to use it and consider whether there are any bans on similar materials, such as ordinary pocket knives or knives. If any of these similar items are prohibited, it is likely that the butterfly knife will also be prohibited.

Another point to keep in mind is where you can carry the pocket knife. There are places where even butterfly knives with no edge on the blade cannot be used or carried. If you are unsure about the legislation, one way to avoid any hassle is to buy a butterfly knife whose blade is not shaped like a penknife blade. In this case it will probably not be considered a perforating or cutting material and will be allowed to be used. There are models of butterfly pocketknives that have a blade shaped like a bottle opener or a comb, as we can see in the photo below. Depending on your case, this may be a good option.

Buying criteria: What to take into account when buying a butterfly pocket knife?

Now, let’s list the points you need to take into account before making the decision of which butterfly pocket knife is best for you:

  • Blade Hardness
  • Blade material
  • Bolt or rivet
  • Coating

Below, we will detail each of these items so that you can make the best choice when buying your butterfly pocket knife.

Blade Hardness

The higher the hardness of your blade, the better the cut of the butterfly pocket knife and the less the wear of the blade at the moment it is pressed against some material. As you can see in the comparison table of the 5 models above, the blade hardness changes from case to case. The main acronyms used to describe the hardness of a material are as follows:

  • 54HRC or 55HRC: generally used in kitchen knives. In general, blades with this specification require regular sharpening.
  • 56HRC, 57HRC or 58HRC: harder material and also frequently used in knives. Requires sharpening only after a prolonged period of use.

Blade material

The different types of stainless steel used in blades have different acronyms for each different combination of amounts of iron and other materials used in the construction of the blade. One option of stainless used is 440C, a material that is quite resistant to corrosion. Among the models of butterfly pocket knives found in the market, 440C steel can be considered the top of the line material. Another material option is known by the acronym 5Cr13MoV. This is a material with good corrosion resistance, but with lower wear resistance that is a bit lower than 440C. In other words, if you sharpen the 5Cr13MoV blade too often, it can become deformed more quickly than 440C.

Screw or rivet

In order to be able to make flippings (opening movements) in the best possible way, the blades should ideally be neither too firm nor too loose. In general, rivets are used in lower quality butterfly pocket knives and screws in better models. In any case, riveted butterfly knives also tend to work well and usually have good durability. Rivets are a kind of fixed shaft on which the blade will be placed and can rotate around it. With these models, you cannot tighten or loosen the blade as the rivet is something that does not allow for any adjustment. The screws, on the other hand, allow you to adjust the tightening to your liking. The tighter you use, the more force you need to open the butterfly knife. If you can see the product up close (it will probably be difficult to see in pictures), notice if the screw has washers or bearings. If it does, it will be even better. These small parts help to improve the opening and closing movements, which can be done with greater fluidity. If you opt for a butterfly screwdriver, remember that the ideal is to check the tightness of the screws from time to time. If the screws get too loose, they can come loose and get lost, due to their small size.

The handle of this type of pocket knife can be made of different materials. The most common ones are metal, wood or some kind of rubberized material or plastic. There isn’t one best, just the one you like best, either for style or for firmness when holding. Some models with metal handles even have drawings, giving more style to the butterfly knife. This type is also usually more durable, as well as the wooden ones. (Featured image source: SnaXXy / Pixabay)
