发明名称 Single handle post hole digger
摘要 The present invention is directed to a single handle post hole digger. The single handle of the post hole digger includes an outer elongated vertical handle and an inner elongated vertical shaft that is located within the outer handle. The post hole digger includes two blades used to cut into the ground and to loosen soil when open and then used to capture and remove soil when closed. The single handle configuration allows for deeper holes as the holes do not have to accommodate the opening action of the handles as in traditional diggers.
