Abstract
A hand-held razor of the wet-shave type includes a thin flexible foil member with a plurality of apertures, each of which has opposed sharpened shaving edge portions. A displacing mechanism cyclically displaces the foil along a predetermined path such that the velocity of the opposed edge portions caused by the mechanism is substantially greater than the speed of motion caused by normal shaving stroke manipulation. The amplitude of each displacement cycle is greater than the width of a beard hair and less than the distance between the oppoosed edge portions.
