Unknown Awasedo Fine Grit Japanese Natural Sharpening Stone 3lb. 5oz. (1502g)

203mmX77mmX39mm

 

It looks very nice shape but the one of the bottom corner does not have a piece, and it looks it happened when the stone was made. It is heavy condensed stone.

 

 

Hardness-------------8.7

It raises very good amount of slurry quickly.

It is hard side in Japanese fine grit stones, and it is finest class side in the fine grit stones.

It looks it does not need tomo nagura or the device to raise the slurry (worn Diamond lapping stone), because it is smooth on the sharpening surface.

(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 kasumi blade knife Jigane became light frosted silver color to semi-mirror finish, and Hagane became mirror 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 3the 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.
