I have the smaller of these two knives. Someone early in the thread posted a photo. The locking mechanism is great, I have plenty of faith in it.
I'll also agree that the clip and its screws are utterly useless without locktight, even then, it is the sorriest clip on any folder I own, even a cheap S&W knife has a much stouter clip.
As for the edge, I royally screwed up a few years ago, and mine is now basically ruined. I was at a well-known knife shop, that will sharpen customers knives. The guy that always did this was really good. Well, long story short, he wasn't there that day. When I handed my knife to the "other" guy, a friend walked in at that exact moment and spoke to me. While my head was turned, the moron laid my A-F on a polishing wheel! He not only ruined the really good serrated section (that I normally detest), he rolled the bevel so badly that it will be hours of work to get it back in shape. Made me sick to my stomach. I don't even get the knife out of the safe now. Oh well.
As for legality, here in TN the smaller of the two versions is legal to carry, the original isn't. But the original also lacks the locking mechanism that makes the smaller version so safe.
