A safety razor includes a handle and a head portion. The handle has a first end portion with a handle aperture and a second end portion. The head portion is removably coupled to the first end portion of the handle and has a replaceable lubrication member, a guard, a replaceable blade, and a cap. The lubrication member has one or more lubrication strips. The guard has one or more notches configured for receiving the lubrication strips of the lubrication member. The blade has at least one cutting edge. The cap has a projection extending therefrom, and the projection is configured to extend through respective apertures in the blade, the guard, and the lubrication member and into the handle aperture to removably couple the head portion to the handle.

This invention relates to razor blades, and more particularly to laser produced markings on razor blades and processes thereof.

Razor blade assembly (100), comprising in sequence an upper plate (110) with a radius of curvature RU; a first razor blade (120) of the thickness T1; a curved spacer member (130) with a radius of curvature RS; a second razor blade (140) of the thickness T2; and a lower plate (150) having a radius of curvature RL, wherein these elements can be reversibly assembled and mounted vertically in height on a razor handle (160); the first razor blade (120) and the second razor blade (140) have a generally rectangular shape and comprise a front cutting edge (121a, 141a) and a rear cutting edge (121b, 141b) running lengthwise; the first and second razor blades (120,140) in its unloaded state are curved in a cross-sectional plane orthogonal to the cutting edges; and the thickness T1 and T2 of the first and second razor blades (120,140) is at least 0.45 mm, and preferably at least 0.50 mm.

An implement including a first plate and a second plate, each plate having a contact surface which abuts a contact surface of the other plate to establish an interface plane, and a gradient of at least one additive that is more concentrated at the interface plane and less concentrated in decreasing amounts progressing away from the interface plane and the contact surface for each plate, wherein the at least one additive alters at least one property of each plate. Materials with internal gradients and methods of making same.

Razor having a hair-cutting fiber having a hair-cutting section attached to a support in such a position relative to a skin engaging surface that the hair-cutting section is exposed to a user's skin for cutting through hairs when the skin engaging surface is in contact with the skin and moved over the skin. The hair-cutting section has a fiber diameter smaller than or equal to 7 m and is made from a fiber material having a tensile strength larger than or equal to 5 GPa. A shaving method using such a razor is also described.

A safety razor comprise a handle and a head portion. The handle has a first end portion and a second end portion. The head portion is removably coupled to the first end portion of the handle and has a guard, a replaceable blade, a replaceable lubrication member, and a cap. The lubrication member has one or more lubrication strips. The cap has one or more openings formed therein and a projection extending therefrom. The projection is configured to extend through the lubrication member, the blade, the guard, and into the handle to removably couple the head portion to the handle. The lubrication strips of the lubrication member extend through the openings of the cap. The safety razor can include a second lubrication member or a skin tensioning member.
