#4000 to #6000 for medium range in the fine grit for high carbon blade

It is used, but it is in excellent condition. It looks glue on the bottom side, so it might be on the wooden block. I do not know which mine it derived from, and it has beautiful Kiita with Nashiji all over sharpening surface.

Hardness-------------8.4

It raises great amount of dark gray or light black color slurry. It is kind of soft stone. It is very smooth stone, and it does not need tomo nagura or the device to produce the slurry (worn Diamond lapping stone).

(Scale; 1 to 10, 1-3 is very soft muddy rough grit whetstone 3-6 is soft medium grit whetstone, 6-8 is hard medium grit whetstone; 8-10 is fine grit whetstone)

Particle Size----------8.8

It makes my white II steel Hon kasumi blade knife Hagane became from semi-mirror finish to mirror finish. Jigae became light frosted silver color finish.

(Scale; 1 to 10, 1-3 give deep scratch marks to the steel, 3-5 is delete the 1-3 scratches, 5-8 makes the steel cloudy, 8-10 makes the steel semi-mirror finish or mirror finish)

Natural whetstone has wider capacity than artificial whetstone, and actually, we do not know until sharpen blade on the hone for a while. Because artificial whetstone molecules do not break down to smaller sizes, but Natural whetstone molecules are possible to break down to smaller sizes, and those molecules are mixed with sharpened steel molecules, and make Jigane as suitable Jigane color, and Hagane as suitable Hagane color. It is natural mystics.
