Abstract
A ratchet wrench having at least one gear disposed in an opening in the head of the wrench. An upper pawl and a lower pawl are disposed in a stacked arrangement in a second opening in the head of the wrench. The openings are in communication with one another. A lever is connected to the pawls to simultaneously move both pawls between a forward and a reverse position. The teeth on the pawls work conjointly and alternately engage the teeth on the at least one gear as the wrench is ratcheted thereby producing a reduction in the backswing arc of the wrench.
