A cutting member for a shaving cartridge is provided that includes a flat cutting portion, a bent portion, and a base portion. The flat cutting portion has a front cutting-edge portion. The bent portion is intermediate to the base portion and the flat cutting portion. The bent portion and the base portion are made out of one single piece of material. The bent portion is arranged such that it is adjacent to the front cutting portion. The proposed shape of the cutting member resembles a reverse L.

A shaving cartridge (1) with connectors (3) on each side portion of the plurality of side portions (2C) of the housing (2D) and a plurality of cutting members (7). Each of the connectors is operable to permit the side portions to pivot relative to each other. Thus, the housing will assume different configurations and is operable to adapt to and follow a contour defined by a shaving surface.

A shaving system may include a handle, a skin-contacting surface coupled to the handle, one or more blades coupled to the skin-contacting surface, and one or more sensors configured to record sounds generated during use of the shaving system.

A method for manufacturing a razor cartridge component comprises continuously feeding an elongated band of material, separating one or more blade support elements from the elongated band of material, stabilizing the one or more separated blade support elements in a stationary position; providing one or more razor blades; and laser welding the one or more razor blades to respective ones of the stabilized one or more blade support elements.

A shaving razor having at least two independent blade assemblies coupled to substantially rigid linkages. The linkages each defining a pivot point between the two independent blade assemblies. A bridge spans between the linkages such that movement of the bridge causes pivoting about the pivot point enabling reciprocating motion of the blade assemblies where assemblies on opposite sides of the pivot point reciprocate in opposite directions.

A method of optimizing a manufacturing process or a blade array of a razor cartridge using spatial information for a tip portion of a razor blade comprises the steps of: measuring, using an atomic force microscope including a probe having a high aspect ratio of a length to a half side angle and a probe tip with a radius less than a radius of an ultimate tip of the tip portion of the razor blade, the spatial information by traversing the probe across the tip portion of the razor blade; analyzing, by one or more processors, the spatial information as measured by the atomic force microscope, to determine one or more blade characteristics; and using the blade characteristics to adjust the manufacturing process to improve a design of the razor blade or to adjust a design characteristic of the blade array to improve a design of the razor cartridge.

Described is a razor with a removable cartridge. The cartridge may attach to a handle magnetically or via another fastening technique, and may include a rigid mechanical structure that may not obstruct any water flowing through the cartridge when rinsing it. This may improve rinsing away clogs around the blades, hair, lotions, or other items, which may reduce the effectiveness of the razor and potentially lead to issues such as razor burns or razor rash.

A shaving razor having a cartridge containing a razor blade coupled to a monolithic yoke. The yoke is formed from a single piece of material possibly by injection molding. The yoke has a bridge and a pair of cross pieces each coupled to the bridge by a living hinge. The cartridge is coupled to the cross pieces and spans between the cross pieces.

A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

A method for re-coating a razor blade (30) of a razor cartridge (10) comprises removing the razor blade (30) attached to a blade support (40) from a housing (20) of the razor cartridge (10). The method also comprises inducing a relative movement between a PTFE material and an edge (32) of the razor blade (30) attached to the blade support (40) to deposit PTFE onto at least a portion of a surface of the edge (32) of the razor blade (30) to form a re-coated razor blade (30) attached to the blade support (40). The method further comprises arranging the re-coated razor blade (30) attached to the blade support (40) into a housing (20) of a razor cartridge (10). A device (100, 200) for re-coating a razor blade (30) is also disclosed.
