Here's a few of mine. The Blackjack Rio Grande is one sweet knife, I wish I had another that I could beat around some. The Tigershark is the original in SK5, the other SOG is the original Sog Tech (also in SK5), the littlest guy on the left is marked "Colorado Cutlery Made In USA", with what appear to be G10 handles, but I can't seem to find any more info about it.
