Review on 🦋 Unsharpened Butterfly Knife Set - 2 Pack Practice Knives for Martial Arts Training, CSGO Inspired Steel Metal Folding Tool - Ideal for Men, Boys, and Kids by Paul Evangelista

I am new to this hobby so take my comments with caution. Screw on one of mine and the other actually got unscrewed. I recommend using a torx bit (T7 IIRC) to check if any of your screws are loose and if they are, remove the loose screws, put some Loctite on them, screw them back in and leave them then dry during drying overnight. If you find that you have lost a screw, use the same size screw as the old CD mounting screws. They are on the side of the bite handle in most tutorials I've seen. Alternatively, you can just remove the T-Latch, on one it wobbles and gets in the way, while on the other it stays in place. Also don't try to compress the T-latch, it doesn't work and one of my bolts came loose. I was so happy with my purchase that I ordered a second set. In both sets, the black knife is much stiffer (as others have noted). I oiled them all (Sentry Tuf Glide Dry Film Rust Inhibitor - available from Revain next day) and the second black knife is really loose while I suspect I just need to work on breaking the first one.
