I picked up a couple of Schrade Cutlery (pre-1946) "ring openers" at a flea market in Winnipeg over the weekend. Both knives have men's names etched on the back of the main blades. The name etchings closely match the "STAINLESS STEEL" etch on the front of the blades, so I'm assuming they were done by the factory. There is no advertising on either knife. Does anyone have an idea of the reason for the names? Has anyone seen similar knives? Thanks for any help.
