ABSTRACT:
The subject invention provides a post hole digger which facilitates the digging of deep uniform diameter post holes. Th post hole digger accomplishes this by crossing the handles to close the shovel blades. This allows the handles to stay within the diameter of the hole opening, removing the need to increase the diameter of the hole opening as the depth of the hole is increased.
