A safety razor shaves back hair of a user. An elongated back shaver handle has a grip and a blade end. A blade group has a sharp blade and a guard parallel thereto. A substrate structure is coupled to the blade end. The substrate structure is adapted to hold both the blade group and a support on a front surface with the blade group and the support spaced a distance. The blade group and the support each extend from the front surface of the substrate structure at a height sufficient to avoid loose skin of the user touching the front surface of the substrate structure. The support can be either a blunt protrusion or another blade group.
