Thread: What kind of japanese hone is this ?

I bought this hone about a year ago when my wife and I was last in Tokyo, at the Morihei hone shop that is mentioned elsewhere on this site.
Unfortunately we were very much in a rush to get to the airport at the time, so I'd told my wife (who speaks japanese) that I'd like a hone for razors, preferably hard, and the approximate price range. I wasn't looking for a high-end natural hone, just something decent to get me started exploring them. I think it was about $200 but I'm not sure. I didn't have time to get the details about this hone, but Mr. Morihei did mention that I should use just a little water and not work up a thick slurry. Next time we go there I'll certainly allow more time for the visit, as it would be very interesting to see a couple of different types of hones and learn some more from Mr. Morihei.

Any information you may be able to provide is appreciated, as I have no experience with japanese natural hones or how to use them.
