#52 Shobudani Uchigumori iro-mono colored stone.
This stone has a complicated pattern of darker rust red blotches against a ligher but intense yellow back ground base. Not the finest stone but it could be used as a prefinishing stone. It is grit rich and it does cut very well and I suggest for razors as a handheld stone that it be mounted on a wooden block so it sits a little bit higher off the palm of your hand. It will be shipped with a piece of Odori nagura which is a similar stone to the Mikawa botan slurry stone.
