Abstract
A wet-shaving razor unit having at least one vertically-displaceable blade responsive to forces encountered during shaving. The razor unit also includes laterally-disposed vertical return springs extending from and continuous with both ends of the razor unit for supporting the blade. The return springs allow vertical displacement of the blade in response to forces encountered during shaving and return the blade to a resting position in the absence of such forces.
