What to use for flattening hones?
I would like some advice on what to use for flattening hones. I plan to get a Norton 220/1000 combo or Naniwa stones (do these come in combos?). I've read on using sandpaper. What grit would I need to flatten these hones? Is using sandpaper economical or will I use it up fast? I would be interested in hearing of other alternatives.
I also plan to get a finishing stone for razors. Not sure of what to get at the moment; maybe a barber's hone, or a water stone. I heard the Chinese 12K was a good economical choice, but the Norton and Naniwa are all I've found where I live so far. Can I get one grit for flattening hones or do I need to get more if I go higher: 200 to 10 or 12K hone?
Thanks for help
