摘要：
The asymmetrical head of a shovel incorporates a vertically oriented metatarsal edge extending upwardly from the tip of the head to a recessed offset dorsal edge offset along the entire length of the dorsal edge from the tip of the head. The construction of the head permits it to function both as a pivot and as a lever, as well as facilitating the initial penetration of the head in soil.
