Type: KME Stones
Tsushima Whetstones are used for fine sharpening on KME or Hapstone knife sharpeners. Tsushima is a natural stone with an estimated grit approximately 5000 JIS.
Tsushima (対馬) Whetstone is mined on Tsushima Island off the coast of Nagasaki Prefecture in Japan.
Tsushima is preliminarily lapped and does not require lapping after purchase. Tsushima 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.
Advantages of aluminum blanks
- If you accidentally drop the stone, it's less likely you break it;
- Much longer life span for the stone after multiple flattening and lapping;
- Easy identification due to laser engraving;
- Reliable clamping for stones of imperfect shape.
Stones mounted on aluminum blanks are thicker than stock KME stones. We recommend using the thickness compensator if you use stones of different thickness.
