Abstract
A ratcheting tool includes a body and a gear disposed in the body. The gear defines a plurality of teeth on a circumference of the gear so that the gear teeth define a first arc having a first radius. A pawl is disposed in the body so that the pawl is movable laterally with respect to the gear between a first position, in which the pawl is disposed between the body and the gear so that the body transmits torque through the pawl in a first rotational direction, and a second position, in which the pawl is disposed between the body and the gear so that the body transmits torque through the pawl in an opposite rotational direction. The pawl defines a plurality of teeth facing the gear, and the pawl teeth define a second arc having a second radius larger than the first radius.
