Tanjiro Butterfly Knife Trainer Demon Slayer Black and Red

A metal safety latch is included to lock the Blade into place when it is not in use as well as when it is deployed. Also known as a Balisong, a Butterfly knife or fan knife is a folding pocket knife with two Handles counter-rotating around the tang such that, when closed, the Blade is concealed within grooves in the Handles. Butterfly knives are especially useful in situations where it is inconvenient to use both hands to open a knife.
