desertcart.com : GOOD WORKER Butterfly Trainer - Practice Balisong Butterfly Knives NOT Real NOT Sharp Blade - Cool Design - Black Dull Trick Butterfly - Butter Fly Training - Fathers Day Dad Gift K14B : Sports & Outdoors

Review: Great value - Great quality. My 10 year old has enjoyed practicing with this. Good fit and balance
Review: Surprisingly effective trainer! - It’s easy to use, surprisingly high-quality for a trainer knife that’s under $10 so the value you’re getting for this is just insane. It’s smooth right out of the box. I already dropped it a few times and there’s no sign of it getting looser or anything, so it’s pretty durable overall. One thing I notice though is the left handle, the one with the locking metal on the bottom, is a bit heavier than the right handle. I find it easier to do tricks with the left handle, so just keep in mind that the handles might make or break your tricks! Weight distribution overall feels very good. 10/10 for a cheap knife!

### ⭐⭐⭐⭐⭐ Great value

### ⭐⭐⭐⭐ Great for beginners
*by K***. on June 28, 2025*

Lasts a long time and is good for beginners unless you pinch yourself between the handles. Paint only barely scratched off after about 2 years and only from very excessive use. The locking pin on the bottom broke pretty fast. Though the pin stayed on for a long time, it became very loose very fast.
