A butterfly knife is a specialized folding knife with two counter-rotating handles that may be closed over and conceal the blade. The knife can be opened by flipping it from the closed position to one side, revealing the blade in its original orientation on the other side of the handle.
The name “butterfly knife” comes from how it looks when opened; the blade resembles two opposing wings of a butterfly when fully extended.
A butterfly knife is a balisong, fan knife, or Batangas knife. “balisong” comes from Tagalog words meaning “to open.” The name “Batangas” knife is due to its origin place in Batangas City, Philippines, where these knives were first found manufactured by Filipino natives during the Spanish colonization period (1521-1898).
The handles rotate around each other so they can be folded into each other, concealing both the blade and any fingers holding onto them. This makes it possible to perform tricks like flipping them around your wrist while keeping them completely hidden from view (or at least mostly), making it an excellent weapon for self-defense or combat sports like kendo.
In addition to the blade itself, other components make up a butterfly knife. The handle is typically metal or plastic and features finger grooves to provide a better grip. A spring mechanism allows you to open and close the blade quickly.
The butterfly knife does not require this, but you can use the other hand to help stabilize the blade as you flip it open. You may also choose not to use your second hand if you prefer having full control over your weapon while flipping it around in front of your face (and eyes).
A trainer blade is a butterfly knife that has a blunt edge. They are used for practicing flipping techniques and are unsuitable for weapon use. This blade type has no sharp edge and, therefore, cannot be used to cut things or damage people or animals. It is designed specifically as a training tool for learning how to flip your knives properly before moving on to live blades with sharp edges. These are usually made from stainless steel, so they won’t rust or corrode easily like other metals might do over time if exposed directly outdoors, where moisture levels vary greatly during different seasons.
