A hand-held tool for resurfacing wiper blades which may be utilized with the wiper blade still installed on a vehicle. The tool includes a case having a rectangular cross section. Enclosed within the case are two resurfacing stones: a first resurfacing stone having a rougher surface and a second polishing stone for applying a final finish to the wiper blade. One or more float springs are situated inside the case and between the resurfacing stones to apply pressure to the stones and to assure that appropriate resurfacing pressure is applied to the wiper blade.
