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.
