Smooth Push Interference Free Snow Shovel
A hand operated snow shovel that will smoothly transition over expansion joints and uneven heights between adjacent surfaces due to the unique design of the leading edge of the blade. The leading edge of the invention is set at an angle to the centerline of the blade to create an offset which effectively makes the leading edge wider than an expansion joint opening and prevents the leading edge from dropping into the expansion joint. In addition, the leading corner of the blade is curved upwards higher than the acceptable height differences in uneven adjacent surfaces. The upwards curve creates a lifting surface for the blade which will cause the leading edge to raise as it is pushed forward allowing the leading edge to smoothly transition from a lower surface to a higher surface as the blade is pushed forward.
