#6000 to #10000 for final sharpening razor blade or fine finish (finest grit) high carbon blade

It is used, but it is in excellent condition, and I do not know which mine it derived from, but I guess it might be Okunomon, or Ohira or, Okudo, or one of the east side of the mine in Kyoto.

Hardness-------------8.5

It raises very good amount of black slurry quickly. It is not too hard and not too soft ideal hardness stone. It looks that it does not need tomo nagura or the device to raise 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----------9.0

It makes my blue II steel Hon kasumi blade knife Hagane became from semi-mirror finish to mirror finish. and Jigae became little frosted bright 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)

Probably #6000 to #10000 grit with the same as artificial whetstone. 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.
