Abstract: An ergonomic earth-working device includes a horizontal handle having a grip with an outer grip, an inner grip and an inner grip interface. The outer grip's ribbed and contoured surface provides easy grasping, while the inner grip interface connects the grip and handle. The handle connects at one end to a curved upper portion having an arc angle. The curved upper portion also connects to an angled portion vertical portion with an angle offset. The angled vertical portion also connects to a vertical shaft, which is perpendicular to a ground plane and removably attaches to a contoured tool member. The configuration of the horizontal handle, curved upper portion, angled portion and vertical shaft, as well as the location of the grip on the horizontal handle, provide an ergonomic advantage allowing users to direct an earth-working force and the contoured tool member straight down rather than at an angle.
