Abstract: A percussion tool having a shank and a pair of generally planar wing portions extending therefrom is provided with a pair of blades which extend from edges of the wing portion. Each wing portion and the corresponding blades are provided with a cutting edge which is L-shaped such that one cutting blade can readily underlie the edge of a windshield during removal. The shank portion is provided with a collar which defines a bit to connect the tool with a pneumatically operated tool holder. The tool includes a nose portion which may be used to break a small slot in the edge of the windshield to receive one wing and blade. The tool is then driven around the circumference of the windshield to sever the adhesive material bonding the windshield to the vehicle and thereby loosen the windshield for easy removal.
