Abstract
Abstract The invention provides the combination of a razor blade 10 and holder 12 for the razor blade, wherein the cutting edges of the blade are constituted by the periphery of a number of holes 10b in the blade, and the holder is provided with means 13 by which the blade can be picked up from a razor blade dispenser 16, the holder maintaining the picked-up blade in an arched condition for shaving. The dispenser may have at least one compartment in which an unused blade 10 can be retained in an arched condition whereby parallel sides of the blade can be engaged by the holder 12 which increases the flexure of the blade to release it from the compartment.
