The snow shovel of the present invention comprises a latitudinal curved blade with opposing end terminus arcs of differing degrees whereby shoveled material will move from one side of the blade to the other. On the back side of the blade are longitudinal and latitudinal ribs forming an integral part therewith providing reinforcement terminating in a centrally disposed receptacle for a handle mounting plate.
The handle mounting plate has mating apertures for fixedly fastening the mounting plate to the curved blade. Positioned at the apex of the handle plate is a post for press fitting the handle plate to the shaft.
The handle grip member also has a post that is inserted into the opposing end of the handle shaft.
The present invention provides means for manufacturing a snow shovel in a lightweight polymeric material that will not deform under load, a property normally associated with metal blades, while the snow moves from one side of the blade to the other due to the decreasing blade face arc.
