I have a knife that has a 4-blade Germany Wade & Butcher Congress Tortoiseshell Handle. It has the Wade & Butcher and Emblem trademark of "Wade & Butcher"  but it also has stamped on the other side of one of the blades; "Germany 016-1992"! I saw somewhere that there was only 100 of these made but don't know for sure. At one time I saw on one of the collector websites where one was sold for $1550.00. Again don't know for sure but I sure would like to know the worth of mine!
