That original Colt one is till around

....and I love that Artificum number that you found...one of my perpetual concerns is the length of the blade since 3 inches is the legally permissible length for a fixed blade knife here in Chicago...I wish that more sghian makers would take that into consideration. There is a class taught up in Mineral Point, Wisconsin (actually, looks like a one day workshop sort of thing) wherein the blacksmithing teacher works with you to make a knife out of a railroad spike. Would LOVE to go up there and do that one...looks like the class fills up really quickly, though.
