ABSTRACT:
A snow shovel including a handle and a one-piece plastic scoop so formed of a minimum amount of material as to resist wear and breakage effectively. It has a self-sharpening reinforcing leading edge, a reinforcing flange at the remainder of its peripheral edge, a series of laterally-spaced reinforcing ribs extending from the leading edge rearwardly, and a centrally-disposed reinforcing keel or rib on its back surface extending from the leading edge to its handle-receiving socket. It also has crush ribs in the socket to allow the handle dimensional variations, prevent rotation of the scoop on the handle, and maintain a snug fit.
