Abstract
Abstract A safety razor head, which may be a replaceable cartridge or part of a disposable razor, has leading and following tandem blades fast with a guard member and a cap member, respectively. The members are pivotally mounted for angular movement independently of each other about spaced axes parallel with the blade edges. Alternatively, the members may be interconnected by flexible bridge portions to provide for the relative angular movement of one member and blade relative to the others.
