Abstract
A wrench includes a shank having two ends and a plurality of recesses are respectively defined in two surfaces of the shank. Any two adjacent recesses in the first surface of the shank are divided by a first rib and any two adjacent recesses in the second surface of the shank are divided by a second rib. The first ribs and the second ribs are located crosswise so as to have better structural strength.
