Abstract
A ratchet wrench is provided which includes a handle having a head on the handle, a rotatable gear disposed in the head and having ratchet teeth, and a pivotable pawl engaged with the gear to allow ratcheting rotation of the gear in a first direction and prevent ratcheting rotation of the gear in a second direction. An obstruction is engageable with a cam surface at the base of the pawl in order to prevent the pawl from self-reversing.
