Disclosed is a new single handle post hole digger for excavating a constant diameter shaft in the ground for setting fence posts and the like. The single handle post hole digger comprises a stationary arcuate shovel blade pivotally connected to a movable arcuate shovel blade. The movable blade has an earth piercing position wherein the movable blade lies parallel to the stationary blade such that the extended arcs of the blades describe a cylinder. The movable blade also has an earth removing position wherein the lower edge of the movable blade is angled inwardly toward the stationary blade to define a scoop. An elongated gripping handle extends longitudinally from the blades. Blade control is accomplished with an actuator lever, pivotally mounted on the gripping handle, connected to the movable shovel blade by a control rod. Moving the lever in one direction positions the movable blade for earth piercing whereas moving the lever in the other direction positions the movable blade for earth removing.
