Galinpo Butterfly Combs Stainless Steel Folding Comb Butterfly Trainer Practice Combs for Sport Outdoor Use (Silver)

Pranked my friend using it and use it for playing a lot more than combing.

Unsatisfactory

There is no cross pin between frames at the pivot area.So if you're gripping the knife, it can bind the whole mechanism.You need hold it loosely. It binds with slightest of pressure.If this would've been a real balisong, it might fall out of your hand and cut you.Better buy some other design.
