Dental floss and metal polish may address the rust at the pivot area. As noted in many SRP posts, Norton 4k and 8k water hones work wonders. More aggressive? a Norton 1k water hone. The Norton hones have been used by many a SRP members that are very happy with the results. For faster work use the 1k followed by the 4k followed by the 8k. Have more time than money? Skipping hones is possible if you want to spend a LOT of time on the higher grit hones or loose some of the smoothness in the shave. Lower grit hones will remove chips faster. Good luck.
