A razor includes an elongated body extending in a longitudinal direction. The elongated body has an outer surface and is provided with a first hole opening on the outer surface. The razor handle further includes an element provided within the first hole. The element is integral with the elongated body and has a shape that is different from the shape of the first hole.

An integrally formed rigid razor blade made of martensitic stainless steel includes a cutting edge portion, a base portion, and a bent portion. The cutting edge portion extends along a cutting edge portion axis and has a cutting edge at one end. The base portion extends along a base portion axis. The bent portion is intermediate the cutting edge portion and the base portion. The blade has a concave face and an opposed convex face. An average radius of curvature of the concave face of the bent portion is between 0.5 millimeters to 0.57 millimeters.

A protector for a razor cartridge is provided. The protector includes a housing extending longitudinally along a longitudinal axis and having a front face and a rear face. The protector further is provided with a first comb disposed on the front face and a second comb opposite the first comb. The protector also includes a first trimming blade has a first cutting edge and a second trimming blade opposite the first trimming blade has a second cutting edge. The first comb and the second comb have several teeth projecting along an axis that is oblique to the longitudinal axis defining a trimming length. The trimming length is adjustable. The teeth of the first comb protrude forwardly with respect to the first cutting edge and the teeth of the second comb protrude forwardly with respect to the second cutting edge.

An apparatus has a first pressure head on a first body, a second pressure head on a second body, a mechanism between the first and the second bodies, adapting the first and the second pressure heads to close together and to open, a substantially planar sacrificial anode joined to the first pressure head on a surface facing the second pressure head, a force mechanism between the first and the second bodies providing force urging the pressure heads together, and a manually operable mechanism adapted to counteract the force mechanism to separate the pressure heads.

A razor assembly comprising a first razor head member; a second razor head member; a handle; and wherein the first razor head member and the second razor head member are pivotable about each other.

This slit blade block includes multiple comb teeth adjacent to multiple outer blade pieces. Each comb tooth has a leading end surface, and a protruding part protruding in a direction away from the outer blade pieces. The protruding parts include an apical part that is the outermost end in said direction away from the outer blade pieces. The leading end surfaces of the protruding parts are positioned between the leading end surfaces and the base end surfaces of the adjacent outer blade pieces. Length L1 in the height direction, defined by the apical part of the protruding parts and the leading end surfaces of the protruding parts, is less than or equal to thickness L2 of the outer blade pieces, defined by the leading end surface and the base end surface of the outer blade pieces.

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.
