Butterfly knives, balisong and training butterfly knives

Butterfly knives, also known as balisong or butterfly knife, are folding knives with two rotating handles that fold around the blade. This mechanism allows quick opening and unique handling, making these knives popular among collectors and flipping enthusiasts.

Butterfly knives are available with standard blades or training blades called balisong trainers, used to practice flipping safely without a sharp blade.
