Abstract
Abstract A one-piece razor handle molded from resilient plastic has spaced-apart opposing side walls joined at an intermediate location by a neck. The walls diverge upwardly from the neck into upper portions for gripping a blade cartridge, and extend downwardly to a spacer that extends between the lower portions of the wall. The lower portions of the walls, between the neck and spacer, are resiliently squeezable. The neck acts as a fulcrum so that the upper portions pivot outwardly as the lower portions are squeezed inwardly. A base joins the bottoms of the walls extending past the spacer.
