About This Item

Ohira Uchigumori 2lb. 5oz. (1048g) Japanese Natural Sharpening Stone

122-145mmX86-95mmX31-35mm

The sharpening surface is finished by chisel, and it is not flattened yet. They are basically close to flat stone, and some bumpy portions. They are possible to use as sharpening stones or finger stones by breaking down. Japanese sword whet masters need to make unique sharpening surface like convex shape, so usually, Uchigumori stone is not flattened in new condition like this one. In general speaking, Uchigumori is soft hone, and lines are very soft, so they do not bother for sharpening. Ohira Uchigumori is the one of the best quality of Uchigumori in Japan Uchigumori is usually entry class of the fine grit hone, and I guess that it might have pigment or oxidized substance, so it gives the Jigane and Hagane vivid color, and it is not super fine, so it deletes or hides the scratches. If you have experience after used finest grit hone, and it leaves scratches and ugly finish, Uchigumori might help delete or hide the scratches, and it makes little hazy very nice finish. Ohira Uchigumori has Hato (Habiki) and Jito (Jibiki). Hato is little softer than Jito, and it gives great result for Japanese sword Hagane finishing process. Jito is little bit harder than Hato and smaller particles of slurry, and it is heavier or little more condensed than Hato is. It gives great result for Japanese sword Jigane finishing process. It is also great result to make up Jigane for kasumi look or Damascus look. It also gives great result for high carbon stainless steel blade removing burr or as finishing 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 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 and iron molecules, and make Jigane as suitable Jigane color, and Hagane as suitable Hagane color. It is natural mystics.
