I agree with Ryan. If you want to pursue honing a lot of old razors for the fun of it the Norton 220/1k and 4/8 combos will be fine. Add a DMT D8C continuous diamond plate for lapping and that is all that you really need. Wet and dry 325 or so sandpaper on a flat surface can take the place of the diamond plate. If you stick with it the plate will be worth the price.
