Abstract
A pawl for a ratchet wrench to be engaged with a ratchet gear. The pawl has a slot formed on each side of the pawl. The slot extends between the top and the bottom of the pawl near the teeth on the front of the pawl. The pawl flexes to compress the slot when torque is applied to the wrench and engagement between the teeth on the pawl and teeth on the ratchet gear is improved.
