A blade assembly includes a housing having a recess defining a first wall on a first side of the housing and a second wall on a second side of the housing, an elongated body that is attached to the first and second walls and is rotatable about a longitudinal axis (S-S), the elongated body having two or more facets, at least one of the facets has a lubricating element disposed thereon, and a locking mechanism for releasably locking the body in a use position.

Disclosed are a razor assembly, and a razor handle and a razor cartridge which are applied to the razor assembly, the razor assembly including: a razor cartridge including a plurality of blades including cutting edges, and a blade housing accommodating the plurality of blades in a longitudinal direction; and a handle coupling with the razor cartridge, and including a head, an interposed element provided at a first side of the head, and a grip extended from a second side of the head, the interposed element being accommodated inside the razor cartridge and interposed between the plurality of blades.

Provided is a razor cartridge including: at least one razor blade having a cutting edge formed therein; a blade housing accommodating the at least one razor blade in a longitudinal direction; and a housing cover comprising a razor blade window and a window frame, the razor blade window through which at least a portion of the cutting edge is exposed, and the window frame which is formed to surround at least a portion of the razor blade window and detachably coupled to the blade housing. At least one of the blade housing and the housing cover includes a detachment part for separating at least a portion of the window frame from the housing cover by an external force.

Provided is a razor cartridge including: a first blade having a first base portion and a first cutting edge formed therein; a second blade disposed in front of the first blade to be adjacent to the first blade, and having a second base portion and a sliding edge therein; and a blade housing supporting the first base portion to have at least a portion of the first cutting edge exposed, and supporting the second base portion to have at least a portion of the sliding edge exposed, and the second blade is formed so that a ratio t.sub.3/t.sub.4 of a thickness t.sub.3 of the sliding edge to a thickness t.sub.4 of the second base portion is less than 1 and greater than a ratio t.sub.1/t.sub.2 of a thickness t.sub.1 of the first cutting edge to a thickness t.sub.2 of the first base portion.

A shaving device comprising a head assembly having a support member and a blade cartridge. The support member is configured to be detachably coupled to a handle. The blade cartridge has a first and a second face wherein at least one of the first or second faces comprises at least one razor blade. The blade cartridge is configured to be rotatably coupled to the support member about a pivot axis such that the blade cartridge is pivotable by a user to select one of the first or second faces.

A shaving device comprising a handle, a support member, a blade cartridge retention frame, and a replaceable blade assembly. The support member is disposed about a first end of the handle and includes at least one arm extending outward from a yoke. The blade cartridge retention frame includes a blade cartridge retention frame magnet and is coupled to the at least one arm and configured to pivot about a pivot axis. The replaceable blade assembly includes a blade assembly magnet and a blade assembly body having a face with a razor blade. The blade assembly magnet and the blade cartridge retention frame magnet are configured to create a repulsive magnetic force therebetween to releasably couple the replaceable blade assembly to the blade cartridge retention frame.

A skin engaging member suitable for use in a hair removal device, said skin engaging member comprising ethyl vinyl acetate having a low level of vinyl acetate and a water soluble polymer.

A safety razor shaves back hair of a user. An elongated back shaver handle has a grip and a blade end. A blade group has a sharp blade and a guard parallel thereto. A substrate structure is coupled to the blade end. The substrate structure is adapted to hold both the blade group and a support on a front surface with the blade group and the support spaced a distance. The blade group and the support each extend from the front surface of the substrate structure at a height sufficient to avoid loose skin of the user touching the front surface of the substrate structure. The support can be either a blunt protrusion or another blade group.

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.
