Great for beginners and smooth to flip
I got this trainer butterfly knife to safely learn tricks without worrying about cuts, and Iโm really happy with it. Itโs well-balanced and has a solid feelโsurprisingly 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. Iโve dropped it more times than I can count, and itโs holding up really wellโno 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 canโt 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!

Great quality, sturdy. The lock is really strong though and tough to locka nd unlock, however Imd rather it be harder to locka nd unlock than it be too easy

Perfect for practicing tricks safely!
I'm really impressed with this trainer,sine the blade is dull and not sharp at all,I can practice new flips and tricks without worrying about getting cut.

Screws come out and may be lost
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 isnโt 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.

Good for a newbie
This is a fun practice device, fit the hand well and is balanced.Well. but it did not hold up very well. The movement is smooth and the sound it makes is pleasant as you're training with it. It lasted just over a month or twenty to twenty five hours practice time, before it broke, I would have to say it's probably worth the money as an introduction. If you are focused on building skill or technique then buy an upgrade.
