Rebound shock as well as hand and wrist fatigue associated with the use of a large wrench, is alleviated by a covering at least the butt end of the wrench with a sleeve, or gripping device, constructed from an pliant and deformable material, such as soft rubber. The gripping device may be provided for attachment to the elongated handle of a tool. It includes a sleeve dimensioned to encircle the tool handle along three sides and to extend along a substantial length of the handle. The gripping device may be mounted on the tool by means of an internal rib or ribs which lock the tool within the device channel cavity. In another embodiment, the device may include a series of finger size undulation along the outer surface to improve the ability of a person to maintain a grip. Because of its configuration and pliant material, the gripping device readily absorbs the impact forces due to torque applied during operation of the wrench that would otherwise be transmitted through the handle, and thereby provides ergonomic shock protection for the craftsperson's hand.
