Abstract
A dual pawl ratchet tool with a leaf spring bias member. The leaf spring includes two bias portions that are coupled to one another by a fulcrum. The fulcrum can be placed in an indent of the pawl pocket to maintain structural stability while applying a bias force against the engaged pawl. In doing so, the bias member reduces the amount of lost motion that is incurred during the ratcheting operation.
