D&Kmall Bottle Opener - Heavy Duty Stainless Steel Beer Bottle Cap Openers, Solid Easy to Use, Unsharpened, for Practicing Flipping, Blunt Practice, No Edge Tool

Great as a trainer or finger fidget. I keep mine at my desk at work and play with it while on hold all the time.Oddly, mine is not like the one in the picture for some reason. The handle and color scheme matches but the “blade” Does not have the socket wrench holes or a bottle opener.I give it five stars because it is a good quality for the price range and I wasn’t really getting it to use as a wrench or bottle opener anyway. But if I was I would be a little disappointed.

This trainer is built very well, it's all-metal and spins very smoothly. The shape makes it much more difficult to do traditional butterfly knife tricks, so be wary of that.After heavy use, the stopping pegs on the blade do wear out the metal on the handle a bit, to the point where the tightening thing on the locking whatever-its-called doesn't go far enough to lock it itself, however the locking-stick-thing is actually tight enough where it uses friction to keep it in place so that isn't an issue.Overall, especially as a starter, I recommend it. It's fun, does the fan super well but for more normal tricks a straight trainer might do better.

Very good trainer, worth the money. Very good for beginners. Would recomend to friends.

My kid asked me to buy him the dull one so he practice his moves. I agreed because no way was I buying a 12 yr old a knife that dangerous. Its cool looking. It's a bit heavy, so thats why I gave it 4 stars. But a neat piece for him to play with and show his friends. Great color and quality for price

Seemed really well made but broke after about a week of my son practicing with it. He wasn't rough on it, just opening, closing, and spinning like it should be made to do.

Flips great, really fun as a curved handle Balisong trainer. Plus, it is a really comfortable bottle opener with a long reach and good leverage. I like the colors, the construction, and the amusing Shark Head design bottle opener. Good Purchase!

This is my second butterfly knife I've bought and is by far my favorite. It's heavy, which feels great considering it's a practice one, and is very sturdy. I've had it for a couple months now and it has lasted. The great thing is that it also comes with extra screws and a tool to maintain it which I've used only a couple times.

Perfect fits nice in my hands one thing it came tight but it doesn't matter
