Abstract: Safety razors comprise frames in which blade members are mounted in such a manner as to permit their angular displacement to change their shaving angle in use. The blade members are pivotally or hingedly mounted and are spring biassed to a normal position in which their shaving angles are at a maximum value. When, in use, the razor experiences high drag forces, the blade members are caused to move so as to reduce their shaving angles. The blade members may respond directly to drag forces applied to them or indirectly in response to deflection of guard members under high drag forces.

Abstract: 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.

Abstract: A razor including an elongated handle and a blade unit at one end thereof and extending transversely thereto. The blade unit is flexibly mounted on the handle and is anchored toward each end to permit the center region to bow inwardly and outwardly.

Abstract: A shaving unit having blade means exposed forwardly of an overlying cap member and rearwardly of a guard member, wherein the blade means and guard member are movable in unison and relative to the cap means against a resilient restoring force in response to forces transmitted to the unit during a shaving operation, to alter the shaving geometry of the unit.
