Abstract: A post hole digging tool has a semi-cylindrical blade member, an elongate handle member, and a pair of hand grip members which can be quickly and easily assembled and disassembled. The blade has a top end wall and a short cylindrical reinforcing ring at its upper end and is semi-circular in transverse cross section. The bottom edge and longitudinal edges of the blade are sharpened to provide soil penetrating surfaces. A threaded collar extends upwardly from the center of the top wall. The handle member is removably connected at its lower end to the collar on the top wall of the blade and extends upwardly in axial alignment with the central axis of the blade and has a tee-shaped portion at its top end. Each hand grip member is removably connected to the lateral ends of the tee-shaped portion and may have an outer covering of resilient material to provide a comfortable gripping surface for the hands of the user and prevent blisters.
