One embodiment of a dual sided razor comprises a handle and a cartridge attached to the handle, the cartridge further comprising a first shaving side and a second shaving side, the cartridge being switchable relative to the handle between the first and second shaving sides.

A miniature disposable nasal razor comprised of a handle, blades, and safety guard, used to remove hair from small confined spaces otherwise unreachable with conventional razors. An efficient inverted U-shape is applied to all blades and safety guard, otherwise maintaining the spatial relationships between blades, and blades and guard, found in conventional straight edge disposable shavers. The longitudinal axis of the shaving head is offset from the longitudinal axis of the handle providing ergonomic benefit to the user.

Methods are provided for the manufacture of razor blades from silicon material. In some implementations, the method includes aligning a mono-crystalline silicon wafer comprising a {100} surface at an angle where {111} planes intersect the {100} surface parallel and perpendicular to the wafer; etching the mono-crystalline silicon wafer to expose an {111} plane and a second plane to provide a blade edge having between about a 20 degree included blade angle and about a 35 degree included blade angle; applying a hard coating on the blade edge; providing a radius of curvature of the blade edge between about 20 nanometers and about 100 nanometers after deposition of the hard coating; applying a soft coating on the blade edge; and removing the razor blade from the mono-crystalline silicon wafer.

The present invention generally relates to blades. Specifically, embodiments of the present invention relate to blades with an hourglass notch in which the hourglass notch functions to secure the blade onto a utility application.

A razor cartridge comprising a housing extending longitudinally along a longitudinal axis, wherein the housing comprises a leading longitudinal side, a trailing longitudinal side, and a cutting member mounting portion in-between the leading and trailing longitudinal sides for accommodating a plurality of cutting members; and a plurality of cutting members disposed at least partially in the cutting member mounting portion, wherein each cutting member is arranged between a leading longitudinal side and a trailing longitudinal side of the razor cartridge in a shaving direction of the razor cartridge, wherein one or more of the cutting members comprises a blade support having a blade mounting portion, and a blade attached to the blade mounting portion.

One embodiment of a dual sided razor comprises a handle and a cartridge attached to the handle, the cartridge further comprising a first shaving side and a second shaving side, the cartridge being switchable relative to the handle between the first and second shaving sides.

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 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.
