Abstract: A digging tool system provides a combination pickaxe and shovel superior to other digging tools in that it effectively allows a user to both break apart dense or impacted material and to move the material with a single tool. The digging device includes a digging head with a generally triangular blade which is capable of penetrating and moving substrate. The blade has a vertically and horizontally curved face, with a greater depth of curve on one side of the horizontal curvature, and a substrate-piercing tip formed by the apex of the blade which is positioned off-center relative to a handle. The greater depth on one side and the off-center placement of the substrate-piercing tip allow for material to be moved to one side as the digging device is pulled through the material.
