Abstract:
This invention provides a post hole digger having a first, traverse pivot point, located on the medial portions of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point of the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.
