Abstract

A safety razor comprises a pivotal cap member which in a first position is effective to obscure the cutting edge of the blade or blade members to protect the cutting edge from contact with other objects. The cap member when pivoted to a second position exposes the blade cutting edge and positions a skin engaging guard surface adjacent the blade cutting edge to provide a desired shaving geometry.
