Abstract
A reversible and a bidirectional ratcheting wrench that transfers multiple torque power from the handle to a nut, or a standard or special socket, by use of flat gears. The oscillating power, applied to the handle of the reversible ratchet wrench is transferred as a rotating motion to a flat gear rotating sleeve. The polygonal inside shape of the rotating sleeve is mounted on a nut or a special socket, completing the transfer of the torque power. The bidirectional wrench utilizes two pairs of gears to insure that each pair creates a different rotational direction of the wrench. A push-pull button mounted in the handle allows the switching from one pair of gears to the other, and from one rotating direction to the other
