6904-063 RHODES "Kriss Kross" safety razor sharpener. You insert a razor blade in the clamp and turn the crank, it strops the blade against a leather wheel and periodically flips the blade over to get both sides. An interesting gizmo from the days before razor blades were disposable. Some loss of nickel plating, in its original box which is very ragged. Good (CVR484) 50 - 100
