Abstract
A wrench including a handle, an open drive portion, and a closed drive portion is provided. The open drive portion and the closed drive portion are located at two ends of the handle, respectively. The handle includes a first side, a second side, and two recessed structures. The second side is opposite to the first side. The recessed structures are formed on the first side and the second side, respectively. The recessed structures are near the ends of the handle, respectively. Both the open drive portion and the closed drive portion have an abutting plane. Each abutting plane forms an angle with an extending axis of the handle.
