Razors are described herein. In some instances the razors include a safety razor blade unit that includes a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap. A first blade defines a blade edge nearer the guard and a second blade defines a blade edge nearer the cap. The first blade has a cutter force greater than the cutter force of the second blade. In some instances the razors provide a comfortable shave having improved closeness.

Method of making a razor

Razors are described herein. In some instances the razors include a safety razor blade unit comprising a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap. A first blade defines a blade edge nearer the guard and a second blade defines a blade edge nearer the cap. The first blade has a cutter force greater than the cutter force of the second blade. In some instances the razors provide a comfortable shave having improved closeness.

Razor blades and razors

Multi-blade razors are provided, having blades with differing properties. In one aspect, a razor is provided that includes a safety razor blade unit comprising a guard, a cap, and first, second and third blades with parallel sharpened edges located between the guard and cap with the first blade closest to the cap, the third blade furthest from the cap, and the second blade disposed between the first and third blades, the blades having first, second and third tip radii, respectively, at least two of the three blades having different tip radii, and at least two of the blades having different coefficients of friction.

Multi-blade razors

A safety razor blade unit has cap structure with upstanding fin elements directed perpendicular to the blade edges to define a cap surface featuring low frictional resistance characteristics during shaving. The fin elements are spaced at a pitch distance of 0.3 to 0.7 millimeter, are 0.3 to 1.0 millimeter in height and are substantially triangular in cross-section with an aspect ratio of 2:1 to 4:1.

Razors

A safety razor in which at least part of the skin engaging surface thereof has an adherent coating comprising substantially spherical elastomeric particles in a polymer matrix, the size and concentration of such particles being such that the coated surface has a surface roughness with spaced major and subsidiary peaks.

Safety razors

A razor head or cartridge is provided on its skin engaging surfaces, e.g. caps and/or guard surfaces with an array of closely spaced projections which, in use, produce a pleasant tactile sensation tending to reduce shaving discomfort. The projections may be formed by closely packed flexible filaments, or by moulded fins or pillars.
