A windshield removal assembly, method and blade for same, with the thin metal blade having a unique delta-shape. The blade connects at its narrowed shank portion to the shaft of a reciprocating power tool. The blade has front and rear ends, the front end being substantially straight and wider than the blade rear end. The blade has substantially straight side edges which narrow from the front end to the rear end to about the width of the shaft. Arc portions are formed between the front end and each side edge of the blade. The top edge of the blade forms a non--sharpened top edge on the front end and arc portions, while the bottom edge of the blade forms a sharpened bottom cutting edge which extends across the front end of the blade and along at least half of the arc portions. The blade has sufficient rigidity to cut the urethane bed when reciprocated, and sufficient lateral flexibility to conform to the curved surface of the windshield when pressed thereagainst. The large arc portions, combined with the sharpened cutting edge extending substantially around the arc portions, improve cutting in a generally continuous lateral movement, especially around corners. The straight side edges preferably join the shank at a reduced angle to strengthen the blade, allowing it to be made in greater lengths without breakage.
