The ratchet assembly includes a drive body having recessed grooves for receiving pivotably mounted first and second elongated pawls. Each pawl includes teeth on opposite ends thereof for engagement with the teeth on the ratchet head. A reversing knob assembly is coupled to the drive body and includes a reversing knob and pins for pivotally rotating said pawls between first and second conditions.
