Hmmmmm. Thought about this and motivated myself to do a little digging around the house. Miraculously, I managed to unearth all 5 of them:
At work it would have likely been a Mini-Buck 425 or a USA made in Portland OR Gerber LST. Both with a 2 inch blade. In the pocket of my leather, while riding my old Shovelhead, it would be my early edition Leatherman.
The rest of the time it would likely have been my Schrade Single blade (3.25 inch) Trapper 194OT with the brass liner lock. Just found it in the drawer where I thought it would be, along with an older Endura that I might have had with me if the situation called for it. I grabbed the Schrade, wiped it off with some Simichrome, and passed it over the stone a few times. It's like a razor right now. Thinking I might tote it along for a few days for old times sake. The old Carbon steel Schrades were great. Made in Ellenville, NY if memory serves me. My local independent hardware store used to have blowouts on them the first week of November every year, to coincide with hunting season. I remember buying a bunch of the Trappers for $5.95 each. Still have this one I've carried, and one in a bubble pack. About 6 months ago a buddy of mine was lamenting that he'd recently lost his that he'd carried since he bought it in a Navy PX many, many years ago. You should have seen his face when I tossed him one in a bubble pack, he couldn't believe it.
Fun thread, thanx.
