## Description

desertcart.com : Grand Way Black Practice Trainer with Durable Build – Safe Cool Design – Black Dull Trick – Training Tool – CSGO Fidget Toy – Perfect for Boyfriend, Father, Son, Teens – Birthday Gift Idea K10 B : Sports & Outdoors

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.
Review: This is nice and perfect weight - This is a good trainer. The weight and balance is good and so is the metal. Looks real and feels real

### ⭐⭐⭐⭐⭐ This is nice and perfect weight
*by M***O on July 16, 2026*

This is a good trainer. The weight and balance is good and so is the metal. Looks real and feels real

### ⭐⭐⭐⭐ Pin fell out, how to fix / solve
*by P***M on April 12, 2026*

Loving this thing so far, only issue. A pin fell out. The one that is circled. BUT there is a fix for the durability issue, and I think the people making these should take notes. Threadlocker. Just put some of it, just a little bit, on the middle ridged part of the pin with Threadlocker, and it'll be right as rain. A more permanent fix would probably some compound concrete of some sort, but this I've found seems to be the cheapest and easiest fix. Holds strong and won't fall out anytime soon. Threadlocker is made to withstand vibrations and movement.
