You know, now that I think of it...I'm not sure I can actually remember? Might have actually been the Gerber Mark II I bought when I was in college in the late 1980s, surrendered a few years later to the NJ State Police, because I had no idea double-edged knives were illegal in NJ. I bought it at The Sharper Image retail store in downtown Pittsburgh when I was a sophomore in college, so it never occurred to me that it might not be legal to carry it. I was young and naive.
I used to use it at college and at work in Atlantic City, working on stage crews, for demolishing sets when we were done with them. The serrations were effective at going through canvas. I think up to that point, probably every knife I owned before that was a folder, or at least, I don't recall owning any fixed-blade knives before that one.
During high school, my brother had got himself a Gerber Blackie Collins Frisco Shiv, which made me impressed with Gerbers.
