Abstract:

A hand-manipulated dirt tool, either a spade, shovel, post hole digger or the like, is driven and guided by the hands and feet of the human user, which tool has at least three (3), operative, outwardly-directed, side edges, preferably continuous, namely, a penetrating chamfer, a slicing edge and a chopping chamfer, preferably at at least two different angles and three sizes, either on one side or on both sides. Thus, at least two, outwardly-directed, side edges are chamfer, which can be parallel, with relatively small, entry surface in beginning edge of the tool and, if spade or a shovel, etc., a foot engaged, top portion is provided. Ideally the three side surfaces, as one progresses up the tool, can make forty-five, seventy-five and forty-five degrees to the rear and ideal “vertical” distances of one, nine and one inches, respectively, and exemplary degree, distance ranges and cross-sectional dimensions are also provided.
