ABSTRACT:
A wrench includes a body having two ends and a handle between the ends of the body. At least one of the ends of the body can be used for driving an object. The handle includes an upper face and a lower face opposite to the upper face. An anti-slipping section is formed on each of two end portions of the upper face and the lower face of the handle. Each anti-slipping section includes a plurality of embossed patterns. Since each anti-slipping section extends across the end portions of the handle, the user's hand will not slip during operation of the wrench even though there is oil on the user's hand.
