Disclosed here are shaving razor systems and methods including razor cartridges with a unitary frame having a length and width, a topside and an underside, wherein the unitary frame includes angled joints or bends connecting at least three guards running lengthwise on the unitary frame, the guards separated by at least three gaps in the frame, and at least three blades, affixed to the underside of the guards of the unitary frame, wherein the at least three blades include edges, and wherein the blade edges extend into the gaps in the frame when affixed to the underside of the guards of the unitary frame.

A blade assembly including at least one blade support and at least one blade element having a cutting edge portion. The blade support includes a base portion and a flat portion. The flat portion extends at an angle with respect to the base. The at least one blade is attached to the flat portion of the blade support. The blade assembly further includes a lubricating element. The lubricating element is attached to the flat portion and the at least one blade element.

A trimming assembly for dreadlocks comprises a handle. A cutting head is operatively connected to the handle. The cutting head comprises a cutting head body defining a receptacle at a radial end thereof. The receptacle is structured to receive a dreadlock. A blade protector is positioned axially within the receptacle. A curvature of the blade protector corresponds to a curvature of an inner wall of the receptacle. A blade is interposed between the blade protector and the inner wall. The blade defines a cutting edge at an axial end thereof proximate to the handle. The cutting edge is structured to cut loose hair protruding outwards from the dreadlock as the cutting head is moved along the dreadlock.

A dermaplane razor device, including a first end operatively connected to a second end, the first end including a holder configured to hold a razor blade; the second end configured for handling; a cover lock rotatably connected to the second end and configured to hold the razor blade within the holder, the cover lock including a handle and locking mechanism; where the cover lock rotates to contact the first end and removably fix the razor blade so that a cutting edge of the razor blade is extends past the holder.

A razor blade including a blade body, an expanded coating structure arranged on a surface of the blade body so as to cover the blade body at least partially, the expanded coating structure including one or more expanded polymer microspheres, at least one of the one or more expanded polymer microspheres including a gas encapsulated within a hollow thermoplastic polymer shell. A process for fabrication of same, including providing a blade body, depositing a liquid suspension, the liquid suspension including expandable polymer microspheres dispersed in a liquid uncured polymer precursor, each expandable polymer microsphere including a gas encapsulated within a hollow thermoplastic polymer shell, on a surface of the blade body to obtain a deposit, and expanding at least a portion of the expandable polymer microspheres in the deposit to obtain an expanded deposit including one or more expanded polymer microspheres arranged on the surface of the blade body, the liquid uncured polymer precursor being configured to remain uncured during expansion of the expandable polymer microspheres. A skincare device including such a razor blade. A process of fabricating same, including attaching such a razor blade to a cartridge.

A razor blade has a first and a second portion. The first portion has a cutting edge at an exterior end and is angled relative to the second portion by a bending process. A bent region that can be arcuate is intermediate the first and second portions. The razor blade is manufactured from martensitic stainless steel being mostly iron and having (by weight): 0.40 to 0.60% C; 0.30 to 0.55% Si; 0.70 to 0.90% Mn; 13.0 to 14.0% Cr; 0.50 to 1.0% Mo; and 0.03 to 0.2%, more preferably 0.03-0.1% N.

The present disclosure relates to a method of forming a razor blade and a razor blade. The razor blade extends along a longitudinal axis and comprises a cutting edge portion positioned along a second plane, a base portion positioned along a first plane that is different from the second plane, the first plane intersects the second plane at an angle. The razor blade further comprises a bent portion intermediate to the cutting edge portion and base portion, and an extended portion extending from the base portion away from the second plane. The cutting edge portion, base portion, bent portion, and extended portion are monolithically formed.

A razor cartridge comprising three or more substantially parallel cutting members disposed between a leading longitudinal side and a trailing longitudinal side of the razor cartridge in a shaving direction of the razor cartridge. Each of the cutting members comprises a blade support comprising a blade mounting portion disposed on an inner surface of the respective blade support that, in use, faces away from a shaving plane, and a blade attached to the blade mounting portion. The cutting members are disposed to define a plurality of inter-blade spans between cutting edges of the blades. A leading inter-blade span that is closer to the leading longitudinal side of the razor cartridge than a trailing inter-blade span is different to the trailing inter-blade span that is closer to the trailing longitudinal side of the razor cartridge than the leading inter-blade span.

A shaving blade member may include a first portion disposed in a first plane, wherein an end of the first portion includes a tapered cutting edge; a second portion extending from the first portion and disposed in a second plane, the second plane being at an angle with the first plane; wherein the second portion comprises one or more protrusions, the one or more protrusions being movable relative to the second portion.

An integral razor blade which is thin and has improved strength by shaping a geometrical structure of the razor blade and a razor cartridge using the same. The razor blade includes a base portion, a bent portion extending in a bent manner from one end of the base portion, and an edge portion extending from one end of the bent portion, a cutting edge being formed at one end of the edge portion. A first separation distance X between a straight line extending in a longitudinal direction from a front surface of the base portion and an end point of the cutting edge ranges from 0.3 mm to 1.0 mm.
