  • Patent number: 5120098
    Abstract: 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.
