#2001 hard dense gray tomae form Oozuku. 
This awasedo stone is fine enough for razors but large enough to last a lifetime honing tools. I have gone from 1k bevel set with my Henckels Friodur and on this stone with diamond plate slurry was able to create a beautiful kasumi finish that shaved like a dream. Perfect conformation with a corners ultra flat back and no inclusions. It will be shipped with a tested tomonagura.
