A razor cartridge includes a housing, a guard, a cap and a plurality of razor blades installed between the guard and cap in the housing, each blade including a base portion, a bent portion extending from an end of the base portion, and an edge portion extending from an end of the bent portion with a cutting edge formed at an end of the edge portion, wherein a first distance between a straight line extending from the front of the base portion and an end point of the cutting edge is in the range of 0.3 to 1.0 mm, wherein an overlap size defined as a distance by which the first distance of one of the razor blades is overlapped by an adjacent razor blade located behind the razor blade when the adjacent razor blade is projected in the vertical direction is less than or equal to 0.5 mm.

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 0.4 millimeters and 1 millimeter.

Shaving systems are disclosed that include a replaceable shaving assembly and a cartridge connecting structure for connecting the shaving assembly to a handle. In preferred implementations, the cartridge connecting structure has a magnetic portion configured to help draw the cartridge onto the handle and retain the cartridge in place when the razor is not in contact with the skin, and a mechanical engagement that provides the necessary retention forces required to keep the system intact during shaving.

The multi-sectional safety razor invention bi-furcated the traditional one and a half (1.5) inch single blade into equal pieces ranging from at least 2 and up in number. These smaller square blades bear a hollowed out center hole which allows them to be fixed and looked into the razor head base. The razor base is made of plastic and there are plastic pegs protruding outwardly. The individual segmented razors look in place on the pegs. A clear cover is heat fused to the razor enclosing the segmented razors to the razor head base.

This multi-sectional security razor makes this razor a safe alternative to the existing disposable products as used by the prison systems, hospitals, facilities and the general public.

A razor having a handle, a head and a main blade housing assembly. The main blade housing assembly defines a first end, a second end and has at least one main blade mounted thereon. At least one first extension blade is mounted on a first extension blade housing assembly. At least one second extension blade is mounted on a second extension blade housing assembly. In a stored configuration at least substantially all of the first extension blade and second extension blade are both positioned between the main blade housing assembly's first end and second end. In an extended configuration at least substantially all of the first extension blade and the second extension blade extends beyond a first end and second end of the main blade.
