This razor was most likely imported by the International Cutlery Co. of New York, NY. The razor itself dates to prior to 1891. Silver steel was invented by the Sheffield cutlers of England. It is prized for its superior hardness and edge retention. Quite possibly the first tool steel. Silver steel is so named for its silver-like shine. Other rumors claim silver steel has small quantities of silver in it, although no one has substantiated these claims.
