What is a butterfly knife?

A butterfly knife, also known as a balisong, is a type of folding pocketknife that has two handles that counter-rotate around the tang of the blade. This allows the knife to be easily and quickly opened with one hand by flipping the handles in a specific manner. Butterfly knives are often used for martial arts, tricks, and flipping performances.

The butterfly knife originated in the Philippines and is traditionally used for self-defense and as a utility tool. It is known for its unique design and intricate flipping techniques that can be learned through practice. The handle of a butterfly knife is usually made of metal, wood, or plastic, and the blade can vary in length and style, from straight edge to serrated.

In some places, butterfly knives are considered illegal due to their potential for harm and concealability. However, in other places, they are legal to own and carry as long as they are not used to cause harm to others. It is important to check the laws and regulations in your area before purchasing or carrying a butterfly knife.
