Abstract
A shaving system of the wet shave type includes body structure that incorporates guide structure and fixed skin-engaging structure with skin-tensioning surface structure. Blade structure, carried by the body structure rearwardly of the fixed skin-engaging structure, has a cutting edge extending along the length of the body structure, and movable guard structure is carried by the body structure between and adjacent to the fixed skin-engaging structure and the cutting edge of the blade structure. The movable guard structure includes a series of skin-tensioning crest portions disposed for skin-engagement between and adjacent to the fixed skin-engaging structure and the cutting edge. The movable guard structure is positioned in the body structure in engagement with biasing structure for dynamic movement of the movable guard structure relative to the fixed skin-engaging structure against the biasing structure as guided by the guide structure in the course of shaving.
