Patent abstract

A ratcheting tool has a head and a handle attached to the head. The head rotatably receives a gear ring and receives a pawl that is in operative engagement with the gear ring. A housing disposed in the head receives a spring that is in operative engagement with the pawl so that rotation of a lever causes the pawl to move between a first position and a second position.
