Abstract:
1. A post hole digger comprising: a first shaft pivotally coupled at a pivot to a second shaft, the first shaft and the second shaft each comprising an upper end having a longitudinal axis, a lower end, and a central portion having a central axis, and an upper transition section between the upper end and the central portion; a first blade coupled to the first shaft at the lower end of the first shaft and a second blade coupled to the second shaft at the lower end of the second shaft; wherein the first shaft and the second shaft pivot about a pivot axis; wherein the central axis of the first shaft, the central axis of the second shaft, and the pivot axis generally define a first plane that extends along the pivot axis when the first blade and the second blade are provided in an open configuration; wherein the longitudinal axis of the upper end of the first shaft and the longitudinal axis of the upper end of the second shaft define a second plane that is substantially perpendicular to the first plane; wherein the first blade and the upper end of the first shaft are located on a first side of the first plane when the first blade and the second blade are provided in the open configuration; wherein the second blade and the upper end of the second shaft are located on a second side of the first plane when the first blade and the second blade are provided in the open configuration; wherein the upper end of the first shaft and the upper end of the second shaft may be pivoted away from one another to position the blades in a substantially closed configuration; and wherein the upper transition section of the first shaft and the upper transition section of the second shaft each extend at a first angle relative to the first plane and a second angle relative to the second plane.
