摘要:
An improved snow shovel for reducing the suction of snow to shovel while still maintaining the overall strength of the shovel. The improved snow shovel has a face or blade scoop portion that has an array of vertical or longitudinally extending slots or slits that penetrate through the entire blade scoop portion of the snow shovel. The array is arranged with the slots aligned vertically in a top to bottom arrangement. The slots are disposed in a set of preferably one to two slots per set. The sets of slots are arranged in a symmetric pattern on the face of the shovel to ensure uniform distribution of the reduction of snow to the shovel and to ensure uniformity of the overall strength of the shovel. The shovel face can be flat or curved.
