A blade retention mechanism that includes a body and a catch. The catch is configured to engage a bit. A knurled nut is configured to engage the catch and the body such that it is movable. When the nut is moved between a first position and a second position the catch moves between a first position and a second position. A v-groove is formed in the body and is configured to receive and retain a bit when the catch is in the first position.

A shaving razor cartridge includes a housing and at least one razor blade. The housing extends between front and rear ends. The housing includes a blade support portion and a handle interface portion. The blade support portion is positioned between the front and rear ends. The blade support portion includes a cap and a guard that is spaced from the cap and cooperates with the cap to define a shaving plane. The handle interface portion is positioned between the front and rear ends and includes a front and rear wall. The front and rear walls each include a lower surface and an interior surface. The at least one razor blade is disposed in the blade support portion between the cap and the guard. The lower surfaces cooperate to define a lower opening. The interior surfaces cooperate to at least partially define a handle receptacle that extends to the lower opening.

A razor cartridge is provided comprising: a housing and a blade assembly mounted to the housing. The blade assembly may comprise at least one razor blade defined by a substrate comprising a first portion and a second portion. The first portion may comprise first and second outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet and an end facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. A shoulder may be positioned between the first facet and the end facet of the first section and define a skin-contacting surface.

A razor head, comprising a housing comprising one or more cutting elements, the housing further comprising a first window, and a second window; a substrate-based shaving aid delivery system, comprising a first reel that is rotatably mounted about a shaft, an actuator operationally coupled with the shaft, wherein at least part of the actuator protrudes externally from the housing via the first window; and a substrate carrying a shaving aid on its external surface.

A shaving cartridge with a housing, having a primary guard at a front of the housing and a secondary cap at a rear of the housing. A bridge member having a primary cap surface and a secondary guard surface is positioned between the primary guard and the secondary cap. The bridge member has a plurality of spaced apart ribs extending transverse to the cutting edge of the first blade and defining a plurality of openings. A first blade has a cutting edge. The first blade is mounted to the housing between the primary guard and the primary cap surface. A second blade having a cutting edge extending in the same direction as the cutting edge of the first blade is mounted to the housing between the secondary guard surface and the secondary cap. A width of the bridge member is about 2.5 mm to about 4 mm.

Provided is a razor cartridge including at least one razor blade having a cutting edge, a blade housing configured to accommodate the at least one razor blade, a guard bar disposed at a front portion of the blade housing, and a cap disposed at a rear portion of the blade housing, wherein the blade housing includes at least one support member configured to connect the front portion and the rear portion, a plurality of seating protrusions disposed on the at least one support member and configured to seat the at least one razor blade, and the plurality of seating protrusions include a first seating protrusion having a first height and a second seating protrusion having a second height lower than the first height.

The retainer is operable to secure at least one blade within a housing of a shaving blade cartridge. The retainer extends along a pair of side edges of the housing, between a front edge of the housing and a rear edge of the housing. The retainer includes an upper end portion and either a lower end portion extending substantially parallel to the upper end portion and connected to the upper end portion by an intermediate portion, or one or a plurality of legs extending from an edge of the upper end portion.

A shaving head for a shaver has a side-cap retainer secured to sides of the shaving head. Each of the retainers has a plurality of legs operable to abut various portions of the shaving head, thereby securing components of the shaving head thereto.

A cutting member (1) for a shaving cartridge includes a front side, a back side opposing the front side, and a flat cutting portion (2) with a cutting edge portion (4). Further the cutting member includes a first bent portion (8), an intermediate portion (11), a second bent portion (9) and a base portion (10) that are made out of one single piece of material. The first bent portion is integral with the flat cutting portion. The first bent portion is convex on the back side of the cutting member, and the second bent portion is concave on the back side of the cutting member. The proposed shape of the cutting member resembles an “S” shape or a question mark shape.
