A method of making razor blades, characterized by the steps of providing an elongated, flat strip of metal having a front edge and back edge extending along its length, sharpening said front edge to result in a cutting edge portion (38) extending along said front edge, and weakening a portion of said strip along its length between said front edge and said back edge to result in a weakened portion (32) extending along said strip, a blade portion between said cutting edge portion and said weakened portion, and a removable portion (36) between said weakened portion (32) and said back edge. |
