Butterfly knife - Cutting and Peeling

A butterfly knife, also known as a balisong, is a folding knife characterized by two handles that fold around the blade when closed. The butterfly knife originated in the Philippines and was originally used as an agricultural tool before becoming a weapon. Today, the butterfly knife is mainly used as a collectible knife or as a practice knife for martial arts.

Popular butterfly knife manufacturers include Benchmade, Cold Steel, Kershaw and Spyderco, among others. It should be noted that the possession and use of butterfly knives may be regulated in some areas due to their potential weapon status.
