## Description

desertcart.com : GOOD WORKER 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 K19 B : Sports & Outdoors

Review: Great for beginners and smooth to flip - I got this trainer butterfly knife to safely learn tricks without worrying about cuts, and I’m really happy with it. It’s well-balanced and has a solid feel—surprisingly sturdy for the price. The handles flip smoothly, and the weight makes it easy to practice without feeling too heavy or too light. The "blade" is blunt and safe, which is perfect for beginners (or parents of kids who are into this stuff). No sharp edges, but it still looks cool and gives a realistic feel. I’ve dropped it more times than I can count, and it’s holding up really well—no loose screws or major damage. The latch works fine, though it can get in the way during tricks sometimes (nothing a rubber band or quick mod can’t fix). Great choice if you're just getting into flipping or want a safe way to practice without risking your fingers. Fun, durable, and definitely worth it. Great for kids too!
Review: Woukd recommend - Great quality, sturdy. The lock is really strong though and tough to locka nd unlock, however Imd rather it be harder to locka nd unlock than it be too easy
