INTERPRETATION OF THE STONE

A hard stone with a very smooth sharpening experience that you might find in some Nakayama Namito. Strong cutting speed, good feedback for a harder stone and silky mud produced from the stone.

I found it best suited for edge sharpening producing an exceptionally fine toothy edge on kitchen knives, single bevel like Yanagiba being the best as well as Japanese woodworking tools.

Using the stone I found starting with a surface from a 600 atoma worked best, washing away any mud made from atoma,  a little water to start sharpening produced a fine dark slurry. This worked best for both edge or bevel sharpening. 
As well using a fine nagura also worked very nicely with this stone, Nagura or other finer stone 

A stone best suited for experienced users with great potential for very fine sharpening.
