Abstract
A ratchet wrench includes a body with a head portion and a shaft. The head portion includes a cavity. A rotatable member is received by the cavity and is rotatable about an axis. The rotatable member has a plurality of teeth disposed around a circumferential surface thereof. A reversing member is pivotally mounted to the body, and is movable between a first position and a second position. A pawl is connected to the reversing member such that the pawl moves circumferentially relative to the axis of the rotatable member as the reversing member moves between the first and second positions. The pawl includes a plurality of teeth that intermesh with the plurality of teeth on the rotatable member. Substantially all of the teeth of the pawl remain intermeshed with the teeth of the rotatable member as the reversing member moves between the first position and the second position.
