<p>SNOW SHOVEL A snow shovel has a smooth-surfaced blade. The blade is pivotally connected to the shovel handle. The blade cutting edge extends along both sides of the blade and along the front edge of the blade. The shovel may be used either as a shovel or as a pick to remove snow from the roof of a building. Deep snow accumulations are easily removed from the roof through a combination of picking and shoveling actions which break the snow up into large blocks which are easily pushed over the side of the roof.</p> |
