Abstract: A razor blade is provided that includes a substrate with a cutting edge defined by a sharpened tip and an adjacent facet, a layer of titanium containing material on the cutting edge, a layer of hard carbon material on the titanium containing layer, and an outer layer of polytetrafluoroethylene.

Abstract: In a razor cartridge, a platform portion has a first cartridge section that includes at least one first pair of razor blades position therein. Each of the first pair or razor blades has an at least partially exposed cutting edge. A second cartridge section is also provided and is coupled to the platform portion. The second cartridge section includes at least one pair of second razor blades positioned therein, each of the second pair of razor blades also has an at least partially exposed cutting edge. The razor cartridge can be mounted either temporarily or permanently to a handle and the cutting edges of each of the first and second pair of razor blades face one another so that during a shaving operation, the razor cartridge can cut hair when drawn over a user's skin in either of two generally opposite directions.

Abstract: In a microprismatic shaving element for abrasively removing hair, a substrate defines a plurality contiguous raised portions projecting outwardly therefrom. Each of the raised portions defines at least one hair engaging surface and is located on the substrate in an array that defines an abrasive surface. During a shaving operation as the abrasive surface is drawn over the skin of the user, each of the raised portions successively abrades hair extending from extending from said user's skin leaving the ends of the hair frayed after completion of the shaving operation thereby achieving the feel of a smooth shave.

Abstract: A blade cartridge for a wet shaving device comprises a housing including a lower housing member and an upper housing member cooperating to define a cavity. First and second blade assemblies are disposed within the cavity. Each of the first and second blade assemblies includes at least one blade defining a cutting edge, wherein the cutting edge of the blade of the first blade assembly generally faces the cutting edge of the blade of the second blade assembly to permit bidirectional shaving.

Abstract: A biasing assembly for a wet shave razor is provided. The razor comprises a cartridge and a handle. The handle includes first and second connecting arms extending outwardly from the handle for pivotally coupling the cartridge to the handle for movement between a neutral position and a fully-rotated position. The biasing assembly includes an abutment surface defined by the cartridge and located on an underside thereof, and a biasing member extending outwardly from the handle and having an end which when the cartridge is coupled to the handle is in sliding engagement with the abutment surface such that as the cartridge moves between the neutral and fully-rotated positions, the biasing member exerts a variable torque against the abutment surface.

Abstract: A microreplicated shaving surface includes a substrate having a plurality of longitudinal micro-shaving element projected outwardly therefrom. The micro-shaving elements are arranged in at least one row with each element being spaced away from approximately parallel to the next successive micro-shaving element. Each of the plurality of micro-shaving elements defines a cutting edge extending longitudinally thereof for cutting hair from a user's skin during a shaving operation.

Abstract: In a razor cartridge, a housing is provided having first and second razor blade assemblies positioned therein. The first and second razor blade assemblies each include at least one razor blade and an at least partially exposed cutting edge. The razor blades are positioned in the first and second blade assemblies to allow hair to be cut from a user's skin when the razor cartridge is drawn thereover in either of two generally opposite cutting directions. At least one shaving aid outlet is defined by the razor cartridge and positioned between the first and second razor blade assemblies to allow the shaving aid to be dispensed therethrough.

Abstract: In a method for making a microedged shaving surface a substrate is provided having a polymer layer applied on at least one surface thereof. An edge layer of material is applied over the polymer layer and has a hardness sufficient to support a cutting edge. At least one surface of the substrate is coated with a photoresist material that is positioned over the edge layer. The photoresist material is cured to render areal portions thereof substantially impervious to removal by etching. The photoresist material is then etched so that the areas adjacent to the substantially impervious areas create a plurality of re-entrant profiles. Any remaining photoresist material is stripped away and the edge layer is etched to the exposed discrete shaving elements, each having a peripheral edge and a sharpness sufficient to cut hair. The substrate around the discrete shaving elements is also exposed so that the cutting edges are offset from at least one surface of the substrate.

Abstract: In a progressive hair removal surface a substrate is provided which includes a plurality of protrusions defining surfaces collectively forming adjacent peaks and valleys. A plurality of abrasive members project from at least one of the surfaces forming the protrusion for progressively abrading hair from a hirsute surface as said hair removal surface is drawn there across.
