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: Good product - It's a good trainer it's fun to use it's easy to grab not the best way in my opinion but it's all right durability is seems good and good value would probably buy again if I would ever need another

### ⭐⭐⭐⭐⭐ Good product

It's a good trainer it's fun to use it's easy to grab not the best way in my opinion but it's all right durability is seems good and good value would probably buy again if I would ever need another

### ⭐⭐⭐⭐ Screws come out and may be lost
*by J***Y on January 30, 2026*

Screw on the latch came out within 5 minutes of use. Was gonna return it but then I found it and out some loctite on them. Not a bad fix but this isn’t something I should have to deal with. Other than that, its a fine product. It has the correct weight to simulate a real butterfly knife.
