I have not honed a razor, but am thinking it is time to give it a try. All of my razors have been bought prehoned. I have used CrOx to maintain an edge, but it seems like some of my razors need just a little more. I am not interested in trying to restore razors or anything like that, just want to be able to bring an edge back up to top shape. So I'm thinking about buying my first razor hone. I was thinking about one of the finer Naniwas. Not sure if I should go with a 12,000 or a 10,000. Which would be better for a single touch up stone?
