Natural stone to grind Hazuya and Jizuya.
After the surface is smoothed by Omura-do, Ao-to and Uchigumori-do will make Hazuya and Jizuya smooth enough to use.
Omura is also used as Omote-zuri (reshaping the surface of the stone) for Binsui-do.
In this case, it is more easy to use if you cut Omura-do into 4 or 5 pieces.
