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. The longitudinal blade surface is rotatable about the central longitudinal axis of the blade and handle upon turning the hand grip members in clockwise or counterclockwise direction about the handle axis. The blade member, handle member, and hand grip members can be disconnected from one another whereby the tool may be disassembled and stored or transported in a compact configuration.

A take-apart post hole digging tool comprising: a hollow semi-cylindrical blade member having a top wall at its upper end with a cylindrical reinforcing ring portion extending a short distance downwardly therefrom, parallel longitudinal side edges extending downwardly from said ring portion and terminating in a downwardly curved bottom edge, said longitudinal side edges and bottom edge defining a longitudinal blade surface semi-circular in transverse cross section about a central longitudinal axis, said longitudinal side edges and said bottom edge sharpened to provide soil penetrating surfaces, an internally threaded collar secured on said top wall in axial alignment with said central longitudinal axis, an elongate handle member having an internally threaded tee-shaped portion at its upper end and an externally threaded portion at its bottom end threadedly received and removably connected to said collar and having a longitudinal axis coaxial with said central longitudinal axis, releasable lock means operatively connected with said handle and said collar threaded connection to prevent accidental unthreading upon rotation, and a pair of hand grip members each having an externally threaded portion at one end threadedly received and removably connected in said handle tee-shaped portion to extend laterally outward therefrom and each having an outer covering of resilient material for providing a comfortable gripping surface for the hand of a user, said longitudinal blade surface being rotatable about said central longitudinal axis and said coaxial handle axis upon turning said hand grip members in clockwise or counterclockwise direction about said handle axis and said cylindrical reinforcing ring portion reinforcing and reducing torque stress forces on said semi-cylindrical longitudinal blade surface when rotated in soil, and said blade member, handle member, and hand grip members being selectively disconnected from one another whereby said tool may be disassembled and stored or transported in a compact configuration.
