Butterfly knives, often known as balisongs are two handled knives which counter rotate around the tang so that when closed, the blade conceals in the handle. A competent user can get the blade out of the handles quickly with some very basic handle flips. We have a wide selection of styles and prices from top end models like the Bradley Kimura to econo butterfly knives. For a beginner, any size works, but a heavy handled balisong can hurt your hand. It is usually best to start out with a lighter knife and then after achieving a reasonable skill level, order one with a heavier handle.
