I had an A/F Covert for a while and liked the knife, but when I finally got around to using it, it didn't hold an edge worth a damn. The steel was marked ATS-34, but didn't hold up as well as the G2 or ATS-34 Benchmades I was using at that time.
That was also back in the day before I really learned how to sharpen a knife well, and I didn't know a whole lot about them, but the factory edge was fresh on the Gerber, and after a little use I was quite unimpressed. It got sold or traded, can't remember which. I just know it was an expensive knife at the time, and I had cheaper ones with better feeling handles that held up better.
I've also had a Gerber multitool that I've used for years. It served me well till it got replaced with a Leatherman, but still rides in my car for emergencies.
Any other Gerber that has been used seems to have pretty soft steel(IMHO) that sharpens easily. Some people tend to like this, but I think it sucks... If I want a knife with soft steel that is easy to sharpen, I have a half dozen SAK's that work great, have better edge geometry, and are cheap.
