Proberos® Butterfly Knives Trainer with O-Ring Latch for Beginner, Children, Butterfly Knives Lover & More, Balisong Trainer with Unsharpened Blade for Practicing Flipping Tricks(Black)

high-quality trainer is designed to be dropped—repeatedly—without the handles warping or the pivots losing their tune. Instead of a sharpened edge, the "blade" is a weighted dull plate, often featuring decorative cutouts to ensure the balance mimics a real live blade. Top-tier trainers usually feature crowned (rounded) spines and chamfered handle edges, which prevent the "bite" or pinching that often happens with cheaper, sharper-edged metal handles during a missed trick.

The material and build quality is good, feels sturdy. Only downside is the hinges loose their smoothness after a while, requiring one or two drops of oil to make it smooth again. Which ofcourse, the oil spreads onto your hands as you use them. Bummer.

I have had that product since 8 months and only minor marks on the paint from falling. The latch becomes loose after a while but it doesn’t make any difference. Everything sounded good, worked good, nothing broke and lasted long, based off experience, this is the best trainer butterfly knife/Balisong to get 🤩🤩🤩🤩🤩

Worst butterfly comb lose screws safetypin false off the thing this happened after 1day worst product looking for a refund or replacement I have photos ill share after screws fell of my butter fly comb flying all over the place my advice DO NOT BUY!

It is made up of a good quality metal and is worth the price. Must buy

its my 4th day with the product and the two arms have already started wiggling and making squeaking sounds. I think tightening the screws should fix this but then again one would have to buy a torque screwdriver just for that. overall pretty average product, not for heavy usage.

Good Things: Quality is actually better than expected. The screws are perfectly fitted and allow free movement of the blade and both handles. Weight is also not too light and not too heavy, it's got a perfect weight. Bad Things: When the blade is extended straight, the blade isn't aligned with the handles. The small locking mechanism keeps rubbing the paint of the down part of the handle.

After learning one trick, the screw came off easily. Even after tightening it, it was coming out as if has a manufacturing fault.
