I currently have the FOX 479, 478, (for 3 years) and the newer FOX 599 Black G10 & 599-TK Orange Trainer (for almost 2 years) and I have NEVER had any issues with the screws falling out. I ad one screw come loose a bit, but since I put a little Loctite (Thread Locker Blue 242), I've had NOT ONE PROBLEM with it since and that was over a year ago. All I'll say is that you need to always check your knife at least once a month and lube it (if you're frequently using it). I use one drop of Tuf Glide (from Sentry) on the apex of the blade and I have a Torx screwdriver to check the tautness of the screws to make sure they're tightened, but NOT too tight (as screws may strip, and that can happen with ANY knife manufacturing company). I also own and check my Emerson Combat Karambit that I own as well.
By the way I got my FOX 599 Karambit at the only place you can get them. Since I can't leave the website link all you have to do it just Google: FOX 599 Karambit and you'll find it. Only one person here in the states sells them anyway. Sure I had to wait 2 months, but MAN it was well worth the wait and just as good as the Emerson Kbit. Also, I understood the Terms & Conditions, since I took the time to read the information BEFORE I purchased, whereas others don't and then complain saying: "Where's my order?" Knowing what I have, even if I had to wait for 3 months, it's worth it. These FOX 599 Kbits knives are amazing!!! A knife (to me) is just like a hand gun, you have to make sure it's always working and ready for use. Just my thoughts on it.
Whatever...
