Hi guys,
My first big failure was with a Gerber Applegate Fairbairn combat folder (the large one) which repeatedly failed to stay locked with any sort of impact to the blade. Unfortunately the first time was when I was out in the middle of nowhere and the AF was my only cutting tool at the time. It was one nervous trip. The second time, I was doing some light whittling of a fuzz stick and the blade just folded, then closed onto my fingers. Yo'd think I'd have known better but I did some live cutting practise with it on a rolled newspaper target, the blade didn;t cut, so got stuck and in trying to remove the blade, it folded again. No pressure against the lock. I then found that if you smacked the spine of the blade with even a small amount of force, the lockbar would bounce open. I later heard that this was a reasonably common problem wit the big AF folder. A shame, since in Australia, it cost me just over $300. Mucho dinero.
So I got the AF Covert which is jsut a bit smaller and comes with the secondary safety which completely eliminates the abovementioned problem. Unfortunately, around this time, I started collecting more high-performance working knives and got a whiff of how much better things could be. I'm talking about edge retention and ease of sharpening. I have to admit I'm a forged carbon steel, American Bladesmith, big bowies, sort of guy. I now make knives almost exclusively from O-1 carbon steel. Check out the Mad Dog knives - most are O-1 steel. They cut like crazy and are ace if you aren't just after stain resistance.
The AF Covert's edge is flat spotted in areas, chipped in others and I've broken the tip. Thatsjust with general use - cutting ropes, cardboard boxes, light whittling and the like. I still carry it because its a mean looking bastard.
Cheers.
