The present invention is a light-weight, single handle post hole digger that can include an outer handle and an inner shaft. The post hole digger can have two blade that are used to cut into the ground and to loosen soil when in an open position and then used to capture and remove soil when in a closed position. A first blade can be attached to the inner shaft by an adjustable pin or bolt and a second movable blade can be connected to the outer handle. A link bar can be connected to the outer handle at a sleeve pivot connection and connected to said movable blade at a blade pivot connection so that when the outer handle is rotated, the blades move between an open position and a closed position. The link bar can be disposed generally orthogonal to an axis defined along the length of the outer handle.
