Thread: Japanese Natural Waterstones: What's in the name?

Forgive me if this has already addressed, but I have been wanting to further educate myself on the JNAT's for straights. I understand that my Nakayama Asagi came from the Nakayama mine, but I see so many other names after the mine name like Asagi, Kiita, Tomae, and so on. Where do these fall grit wise? I know we can't rate a natural by grit, but is there an "order" that these and I am sure others fall in? Aoto is on the opposite end of the scale I know compared to my Asagi. Then you get into the nagura'a...is there a scale for those? Any information or links provided would be most appreciated.

Btw...a light thuringian slurry gradually thinned to just water on an Asagi is simply awesome! Just tried it on a Torry yesterday.
