I'm in the other camp than the other guys: if you want to maintain your razors yourself or anticipate you'll be honing your own razors, a 12K Naniwa is an excellent hone. It can be the last step in your progression when you decide to buy extra hones, or used exclusively for touch-ups. You can expect to need touch-ups a little more regularly when starting out with SR shaving, because of little mistakes you make while learning to strop and shave. If your budget is up for it, I'd say get the 12K or even a 16K Shapton, both are good finisher hones.
