This thing worked perfectly. After trying everything else in my toolbox, this tool came to the rescue for removing the wiper arms on my Saab 9-5. The cone shaped piece screws down, forcing the claws to grip the wiper arm well. The center screw then tightens to contact the shaft, safely pulling off the arm with no damage (and no risk to your windshield).
