A manual implement comprises of a handle which incorporates a lever shaft in one portion and a torque and lever shaft in another, and a novel integral blade, blade support and handle socket. The implement presents a twice offset but linear line of mechanical forces which allows the user to loosen, excavate and relocate a load of material without the concomitant hard physical exertion normally necessary to accomplish these steps by efficiently translating a minimum amount of force and action by the user into effective mechanical force and action by the implement.

A manual digging implement for moving material comprising: a handle means with grip means at one end, a handle base at the other end, and a central handle portion curved about one fourth the way from said grip means end to said handle base end so as to position said grip means forwardly of said hand

A manual digging implement for moving material comprising: a handle means with grip means at one end, a handle base at the other end, and a central handle portion curved about one fourth the way from said grip means end to said handle base end so as to position said grip means forwardly of said handle base when the implement is in a normal upright position; integral blade means, blade support means, and handle socket means wherein the lower exterior portion of said socket means is formed to provide an overall implement fulcrum means; said handle base mating precisely within said socket means along complementary arcuate quadrant portions of both; attachment means for securing said handle base to said socket means; whereby minimum physical exertion by the operator is required to effectively loosen, excavate, and move said material.
