FWIW, I lay a straightedge across all the keytops (in a grand, put the keys on the keyframe) and scratch a line with a razor blade where the notches end. I then file up to the line. Be sure not to extend the razor blade mark too far, lest it remain after you file the notch. If you are careful, your notches will line up evenly across the sharps.
