So far of these suggestions, I only have two of them (Mora Carbon companion, and Kabar USMC Fighting Utility). Then again, I'm pretty sure I'm not your stereotypical BF member, as I don't really own many folding knives, and none of the folding knives I own are from Spyderco, Benchmade, or ZT. I do have one old KAI though.
The Buck 110 seems to be a good suggestion (and its been around for forever, helping its chances). I'd also toss in the Victorinox Alox Farmer, as I've seen many people mention they have that one.
Also, what about the forum knives? Not just the forum versions, but the other general models? Weren't the forum knives selected because they were very popular, and people wanted upgraded/customized versions of one? So what about the Kershaw Skyline, or a stockman of some kind? Also, Case peanut anyone?
