Tighten the screws upon unboxing
I would give it a 5 but I got it out of the box and within the first couple hours the screws came out and flew off. Its my fault I didn't tighten it before using but golly they weren't that loose to begin with.

Great for beginners and smooth to flip
I got this trainer butterfly knife to safely learn tricks without worrying about cuts, and I’m really happy with it. It’s well-balanced and has a solid feel—surprisingly 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. I’ve dropped it more times than I can count, and it’s holding up really well—no 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 can’t 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 tool for learning how to open and close a butterfly knife with flair
This is a perfect practice tool. It is sturdy and durable and can withstand being dropped or flung across the room. Don't laugh, it happens when you're practicing. The size and weight are accurate so transitioning is easy.

Decent...
Not bad but, and this may be my inexperience here, the "blade" and handle bits kept knocking into my knuckles while using, not so much as to cause real pain but discomfort indeed, i feel as though the handle is too heavly weighted compared to the blade and this was the cause, but as i said this may be my novelty. The color was nice though not as pearlecent as i'd hoped but still.

Nice for fidgeting.
I wanted one of these mainly just as something to occupy myself when anxious at my desk, and it's perfectly suitable for that! Feels well weighted, the texture is nice. It closes a little rough, but overall construction seems good and like it won't come loose any time soon. Can't really speak to it for any actual knife training.
