If you don't have a hone, you could use your metal polish of choice. I prefer to start with a single edge scraper (looks like a SE blade, but they say clearly they are not for shaving) to take off the top layer of rust. If you put the edge parallel to the razor's edge and make a swipe from spine to edge, all the surface rust should come off quite easily.
