I don't seem to find a lot of the name "Gerber" mentioned; I've been keeping Gerber blades on me since I got my first as a present when I was 16 or so. My favorite was an old AR 3.0 BBS, before I lost it during a camping trip; the one I purchased to replace it isn't nearly as smooth opening no matter how much I work it.
My current "carry" is a Gerber Paraframe, which I have in both serrated and fine edge, and they're the smoothest, fastest opening folding knives in the family (a family with lots of knives, I should add). The Paraframes are also very slim, so they're easier to conceal, I think, than most folding knives I've toyed with. My S&W ExtremeOps folder is smooth, but not as intuitive to hold or as fast to open, and my Ka-Bar MULE folder is great but has no clips to keep it anywhere but in a pouch or loose in a pocket and isn't a one-handed knife.
I find my Gerber knives to be perfect as a concealed, one-handed carrying companion, and often have a couple on me.
So what do you guys think of Gerber folders? Not meant for the defensive roll or good to go?
