ABSTRACT:
The present invention is directed to a razor head having at least one blade with a sharpened edge disposed between a guard member and a cap member. The blade is supported in a manner such that the blade is pivotable about a point directly below, or below and forwardly of, the sharpened edge of the blade. The pivoting blade arrangement of the present invention is particularly adapted to decrease the blade exposure while increasing the guard-blade span and the shaving angle when the blade is subjected to forces during shaving. Biasing members are also provided for returning the blade edges to their original position when shaving forces are not acting on the razor head. While the razor head of the present invention is illustrated in a preferred embodiment as a two blade disposable cartridge, alternative embodiments including a single blade and a completely disposable razor are within the scope of the present invention.
