butterfly knife trainer, practice stainless steel training tool for training and practice, stainless steel (color)

It was good but it started to get a little loose

It's not sharp as really fun to play with. For the price, I think it is just going to be like trendy for a little then not. Jt one of those specialty.

It is quiet, smooth and has a nice weight to it. It is difficult to latch shut. Cool neo-chrome is cool. It does pinch at the hinge occasionally. Good for teens that may fidget a lot.

After a day and a half of rigorous use, the thing basically fell apart. On arrival, the handles were very stiff and wouldn’t move without force, thus making it hard to flip. Even with lubricant, I had to loosen the screws so the handles would move on their own. With the wrench they provided, it wasn’t a perfect fit so I also stripped the screws! On the first day after a few drops (it is a trainer after all), the latch on the bottom became loose as did the handles. (Did I mention the wrench wasn’t big enough so I stripped the screws!) So much for tightening it. After the full day and only like the sixth drop, the pin that holds keeps the blade centered fell out, throwing the trainer out of balance. Overall, cool if you’re looking for a day-week of use before it dies on you. After that, look for other and better built trainers.

It worked how it needed it went flip flip and flip but it is heavy

I know this is an inexpensive knife, but it should at least function when you get it. It did not come with a key wrench as shown. But even if it had, it wouldn't have made a difference. The knife came with the screws much too tight. I have another knife with the wrench, but it wouldn't work. I also have a whole wrench set that wouldn't work. The screws are too tight and the other side is smooth, so there is nothing to grab on to, to loosen or tighten. I just wound up with stripped screws and a useless paperweight. It looks cool though.

My son enjoys using this training knife but often has to tighten up the screw that comes loose with use.

It’s okay I guess. It’s way too tight so it barely spins if at all. One of the screws on it was stripped so I couldn’t really fix it. But hey it’s cheap haha.
