In general speaking, Uchigumori is soft hone, and lines are very soft, so they do not bother for sharpening.

It is already flatten the top surface, so it is ready to sharpen. It has done by one of the whetstone company in Kyoto. Ohira Uchigumori is the best quality of Uchigumori in Japan

Ohira Uchigumori has Hato and Jito. Hato is little softer and rougher than Jito, and it gives great result for Japanese sword Hagane.

Jito is little bit harder and finer than Hato, and it is heavier than Hato. It gives great result for Japanese sword Jigane. It also gives great result for stainless steel blade as finishing whetstone and Damascus pattern cutlery.

***Damascus pattern and Kasumi pattern are hard to come out beautiful finish, but Uchigumori bench stone or Uchigumori finger stone makes really good finish on them.***

Natural whetstone has wider capacity than artificial whetstone, and actually, we do not know until sharpened the blade with the hone for a while.

Because artificial whetstone molecules do not break down to smaller sizes and contains single sharpening particles, but Natural whetstone molecules are possible to break down to smaller sizes, and there are variety of substances in there, 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.
