Atago Whetstones are used for finish sharpening on Hapstone and Edge Pro knife sharpeners.

Atago (愛宕) Whetstone is mined in Japan. Atago is ultra-fine natural stone with the LV4 hard rating.

Atago stones are universal and can be used to sharpen knives of any steel.

Atago is preliminarily lapped and does not require lapping after purchase.

Atago should be used with water as a lubricant. All that is required is to wet the stone surface. There is no need to immerse the stone. During the sharpening, the slurry is released from the stone surface. Try to keep slurry on the stone surface.

Atago stones may have slight natural imperfections, inclusions and other minor defects not affecting the sharpening. Atago stones usually have magnesium lines which look like cracks; this is not cracks.
