Two-point discrimination safety razor assembly

摘要

A safety razor for shaving back hair. A substrate structure at an end of an elongated back shaver handle opposite a grip end holds both a blade group and a support. The blade group has a sharp blade and a guard parallel thereto. The support can be either a blunt protrusion or another blade group. The blade group and the support are spaced a tactile discrimination distance from another blade group and support sufficiently wide enough to achieve two-point discrimination tactile feedback felt through a torso region of the skin of the user.
