  • a handle comprising;

    a first end,a second end opposite to the first end, a first surface extending between the first end and the second end,a second surface extending between the first end and the second end opposite to the first surface,a continuous sidewall interconnecting the first surface and the second surface,a recess constructed and arranged in the first surface at the first end,a lip constructed and arranged along the first surface at the recess and extending inward toward the recess,a protrusion extending from the handle at the first surface intermediate the first end and the second end,a first elevated portion extending along the first surface between the protrusion and the second end,a plurality of ridges projecting from the first elevated portion, each one of the plurality of ridges having a density less than the density of the material from which the remainder of the handle is constructed,an aperture constructed and arranged to extend through the first surface at the recess and the second surface to provide communication between the recess and the second surface,a pair of separate and discrete regions disposed on the first surface between the first end and the protrusion, each region having a density less than a density of the material from which the remainder of the handle is constructed,a second elevated portion extending along the second surface substantially in registration with the first elevated portion,a region of material extending along the second surface between the protrusion and the first end, the region having a density less than the density of the material from which the remainder of the handle is constructed; and
