It makes my blue II steel blade knife Jigane to medium dark dull gray color, and Hagane to light frosted silver color. It should be great stone to make Jigane color to darker than Hagane color.

It is from direct from Ohira mine where has been mining five generations of Ohira whetstones. Ohira mine produces Awasedo (fine finishing whetstone), Suita, and Uchigumori. Ohira is very famous whetstone as Japanese sword sharpening hone as Uhigumori. 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 (it also shows Damascus pattern vividly), and Hagane as suitable Hagane color. It is natural mystics.
