Aoto Whetstone for Edge Pro

  Edge Pro form-factor stones are suitable for Edge Pro, Hapstone, TSProf and all Edge Pro compatible sharpeners



Aoto Whetstones are used for fine sharpening on Hapstone or Edge Pro sharpeners. Aoto is silica natural stone with estimated grit approximately 2000-3000 JIS. Aoto stones are mounted on high-quality aluminum blanks.

Aoto (青砥) Whetstone is mined in Kameoka, Kyoto in Japan.

Historically Aoto was the most common whetstone in Japan to sharpen kitchen knives.

Aoto is preliminarily lapped and does not require lapping after purchase. Aoto should be used with water as a lubricant. Soak Aoto in the water for 2 minutes before use. During the sharpening, the slurry is released from the surface. It's not necessary to keep slurry on the stone surface.

Aoto stones may have slight natural imperfections and inclusions.
