Hammer rebound shock and hand and wrist fatigue associated with the use of a wire seating and/or cutting tool, such as an impact tool, is alleviated by a covering at least the butt end of the tool handle with an internally ribbed cushioning sleeve of elastically deformable material, such as soft rubber. Because of its ribbed configuration and soft rubber material, the cushioning sleeve readily absorbs the rebound of the hammer impact force that would otherwise be transmitted through the handle in the course of operation of the tool, and thereby provides shock protection for the craftsperson's hand.
