Abstract
A ratchet handle for a hand tool employs pairs of opposing pawls which are biased by a spring and selectively engage teeth at the interior of a cylindrical structure to provide for a three direction mode ratchet drive. A shifter engageable at one of three positions has ears which selectively interact with the pawls. In one embodiment three pairs of opposing pawls are biased by a garter spring. Another embodiment employs an integral serpentine spring/pawl assembly.
