The butterfly knife – or butterfly knife, in the translated term – is a pocket knife, created in the Philippines and used in the martial arts of that country. This object has two cables, which can rotate counterclockwise. When they meet at the base, they form a single handle, and hide the blade.

What do you need to pay attention to before buying a butterfly knife?
The first step to observe is whether the butterfly knife has a blade with a cord or without. If you are a beginner, it is recommended to try your first flippings the butterfly knife without blade to avoid accidents. After all, learning is wrong, and you don’t have 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 will rust more easily than the others. In addition to resisting corrosion, the blade must be resistant.
In extreme cases, the blade may break if the material used is not hard enough. To understand how to choose the right blade, be sure to continue reading to understand the acronyms used in describing the type of material.
The second fundamental point is the opening mechanism. There are two types: screw and rivet. We explain in the next section more details about the two options.
What is the legislation regarding this knife?
Before making the purchase, it is worth checking where and when you can use the butterfly knife. Think of the places where you are likely to use it and consider whether there are any prohibitions for similar materials, such as common 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 be taken into account is where you can carry the knife. There are places where not even wireless butterfly knives on the blade can be used or ported.
If you are unsure about the legislation, one way to avoid any inconvenience is to buy a butterfly knife whose blade is not shaped like a knife blade.
In this case, it will probably not be considered a piercing or cutting material and its use will be released. There are butterfly knife models that have a blade in the shape of a bottle opener or a comb, as we can see in the photo below. Depending on your case, this may be a good option.
The price of this product does not vary much. The butterfly knife costs between R $ 60 and R $ 100 in most online stores. Although there are models of price and superior quality, it is not easy to find them online stores.
But the alert is to be suspicious of cheaper products than these prices mentioned, in this case, very cheap products can compromise the quality of the knife.
Where to buy?
Unless you live in a larger city or where there are a lot of interested people, you will probably have a hard time finding butterfly knives in physical stores.
An easier option is to look in specialized online stores: manufacturer websites, large retail store websites, as well as sites Amazon.
Purchasing criteria: What to take into account when buying a butterfly knife?
Now, let’s list the points you need to take into account before making the decision on which is the best butterfly knife for you:
- Blade hardness
- Blade material
- Screw or rivet
Below, we will detail each of these items so that you can make the best choice when buying your butterfly knife.
The greater the hardness of your blade, the better the cut of the butterfly knife and the less wear of the blade the moment it is pressed against some material.
As you can see in the comparative table of the 5 models above, the hardness of the blade 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 often used in knives. It requires sharpening only after a prolonged period of use.
The different types of stainless steel used in the blades have different acronyms for each different combination of amounts of iron and other materials used in the construction of the blade.
An option of stainless steel used is 440C, a material very resistant to corrosion. Among the butterfly knife models found on the market, 440C steel can be considered the top of the line material.
Another material option is known by the acronym 5Cr13MoV. It is a material with good corrosion resistance, but with less wear resistance slightly lower than 440C. In other words, if you sharpen the 5Cr13MoV blade many times, it can deform more quickly than the 440C.
Screw or rivet
In order for you to be able to make flippings (opening movements) in the best possible way, the ideal is that the blades are neither too firm nor too loose.
In general, rivets are used in the lower quality butterfly knives and screws in better models. Anyway, butterfly rivet knives also usually work well and tend to 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 any more since the rivet is something that does not allow any adjustment.
The screws allow you to adjust the grip to your liking. The more tightening you use, the more force you will need to open the butterfly knife. If you can see the product up close (it will probably be difficult to see in photos), check if the screw has washers or bearings. If so, it will be even better.
These small pieces help to improve the opening and closing movements, which can be done with greater fluidity. If you choose a butterfly knife with screws, remember that the ideal is to check the tightness of the screws from time to time. If the screws become too loose, they can come loose and be lost due to their small size.
The handle of this type of pocket knife can be made of different materials. The most common are metal, wood or some type of rubberized or plastic material. There is no better one, just the one you like best, either by style or by firmness when holding.
Some models with metal handles even have designs, giving more style to the butterfly knife. This type is also usually more durable, as are wooden ones.
