## Description

desertcart.com : Butterfly Knife - Balisong Trainer - Black Practice Butterfly Trainer with Sure Spring Latch - Balisong Knives NOT Real NOT Sharp Blade - Full Stainless Steel Fake Dull Trick CSGO Fidget Toy K10B : Sports & Outdoors

Review: Perfect for practice - Bought it for my 9year old because he loves butterfly knifes, great for practice.
Review: Honest thoughts - I was told I had to stop twirling the knives at work as it made others uncomfortable and it wasn't safe. . . So got this as an adult fidget spinner. I don't have nor inspired to own a real butterfly or bala -whatever knife so can't say how accurate it is for training. But it is pretty fun and feels like "tricks" just more or less happen on there own, plus keeps my hands busy. I figured it would be a wobbly, loose, cheap feeling toy but even with over 6-8 hours a day of flopping, dropping, slamming, twirling, spinning, and flipping, it's as good as the day I got it. I almost want to try to break it at this point but then my bored hands would be lonely.
