Abstract
An implement for penetrating soil or similar substances. The implement includes a handle having a gripping portion, a socket having a receiving portion, a work engaging portion, and a step having a foot engaging surface to which the user applies force to drive the work engaging portion into the soil. The foot engaging surface of the step is aligned with the natural orientation of the user's foot by positioning the centerline of the gripping portion or the receiving portion substantially normal to the foot engaging surface. Alternatively, where the implement has steps with foot engaging surfaces lying in first and second planes, the centerline of the gripping portion or receiving portion is substantially perpendicular to a line formed by the intersection of the first and second planes.
