Abstract: A safety razor removes hair from skin using the cutting blade comprising a sharp edge along an elongated side of a planar surface. An outer comb has a row of outer teeth running along the planar surface on an outside of the cutting blade, each outer tooth is substantially perpendicular to the sharp edge and spaced with a gap between the row of the outer teeth and the planar surface of the cutting blade. Ends of the row of outer teeth comprise outer teeth tips. An inner guard runs along the planar surface on an inside of the cutting blade.

Abstract: A safety razor removes hair from skin using the cutting blade comprising a sharp edge along an elongated side of a planar surface. An outer comb has a row of outer teeth running along the planar surface on an outside of the cutting blade, each outer tooth is substantially perpendicular to the sharp edge and spaced with a gap between the row of the outer teeth and the planar surface of the cutting blade. Ends of the row of outer teeth comprise outer teeth tips. An inner guard runs along the planar surface on an inside of the cutting blade. The sharp edge of cutting blade is recessed up to a skin surface contour, the skin surface contour defined by the outer teeth tips and an edge of the inner guard. The sharp edge of cutting blade longitudinally bends to cause further recess relative to the skin surface contour.

Abstract: A back shaver has a body shaver handle and a flexible coupling for a blade cartridge comprising a sharp blade. The flexible coupling uses a material that allows the blade cartridge to pivot with respect to the body shaver handle. In some alternatives the flexible coupling uses rubber or another flexible material. In other alternatives the flexible coupling uses a mechanical pivot mechanism located near the inner side at an end of body shaver handle opposite the handle end and allowing the blade cartridge to move and pivot at alternate angles when pressed against a skin surface. The mechanical pivot mechanism can be located at in the blade cartridge or in the body shaver handle.

Abstract: 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.

Abstract: A safety razor for shaving hair on skin has a substrate structure and a plurality of blade groups arranged in parallel rows on a front surface of the substrate structure, each of the blade groups spaced a distance therebetween. Each blade group has a sharp blade having a leading side and a trailing side for shaving the hair, an outer comb next to and parallel to the leading side of the sharp blade, and an inner guard next to and parallel to the trailing side of the sharp blade. A suppleness distance between the outer comb and the inner guard of each of the blade groups can be narrower than the distance spaced between each of the blade groups.

Abstract: A safety razor shaves back hair. A substrate structure at a blade end of an elongated back shaver handle opposite a grip end 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 leverage feedback distance sufficiently wide enough to provide leverage feedback felt through the elongated back shaver handle for the user to maintain a consistent angle of the sharp blade relative to the skin surface when an arm of the user reaches the elongated back shaver handle to the user's backside during shaving movement over a shoulder blade peak or a spine depression.

Abstract: A back shaver handle has a generally s-shaped elongated member. A grip has a finger surface located on the inner side. A blade attachment at a blade end is located on the inner side. A body leverage surface is located on an outer side of the elongated member near a midway between the grip and the blade end configured to press a body leverage surface against a user's forearm when a finger surface and grip are respectively gripped by fingers and hand with thumb facing away from the blade end of a same arm of the user and the s-shaped elongated member is reaching the blade end under an armpit of the same arm of the user to leverage the blade attachment located on the inner side of the elongated member towards a torso backside of the user.
