Zulu Grey sharpening stones are used for super finish sharpening on KME and Hapstone knife sharpeners. Zulu Grey stones are mounted on high-quality aluminum blanks.
Zulu Grey Whetstone is mined in Kwa Zulu-Natal province, South Africa. Zulu Grey is indurated sedimentary rock with estimated grit 8000-12000 JIS.
Zulu Grey is preliminarily lapped and does not require lapping after purchase. Zulu Grey stones should be used with oil or water as a lubricant.
Zulu Grey stones may have slight natural imperfections, inclusions and other minor defects not affecting the sharpening. Colors range from Grey-Blue to Grey-Green with a fine speckled pattern similar to very rare Tam O'Shanter stones. Some stones may also have orange swirls or stains - this is created by iron oxide present in the stone and is quite beautiful in appearance.
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.
