A snow shovel has a blade ending in a front leading cutting edge of wedge cross section. Rear vanes having coplanar bottom surfaces aligned with the cutting edge, terminate in a rounded trailing edge parallel to the leading edge. The blade leading edge can pivot upward about the trailing edge allowing the leading edge to clear irregular ground. The rear vanes cut through the snow to the ground surface, allowing minimal clearance by the leading edge and close snow removal.
