A reversible and a bidirectional ratcheting wrench that transfers multiple torque power from the handle (20, 120) to a nut, or a standard (71) or special socket (68), by use of flat gears. The oscillating power, applied to the handle (20) of the reversible ratchet wrench is transferred as a rotating motion to a flat gear rotating sleeve (30). The polygonal inside shape of the rotating sleeve (30) is mounted on a nut or a special socket (68), completing the transfer of the torque power. The bidirectional wrench utilizes two pairs of gears (132, 133) to insure that each pair creates a different rotational direction of the wrench. A push-pull button (160) mounted in the handle (120) allows the switching from one pair of gears (132, 133) to the other, and from one rotating direction to the other.
