Chosera sharpening stones are used for sharpening knives on KME and Hapstone knife sharpeners. Chosera is a high-end series from Naniwa made of aluminum oxide with the magnesia binder. The magnesia binder gives Chosera excellent sharpening quality and performance, and high wear resistance.
Chosera series stones are universal and can be used to sharpen knives of any steel.
Chosera stones are preliminarily lapped and do not require lapping after purchase.
Chosera should be used with water as a lubricant. Do not soak Chosera stones in water for more than a few seconds. Just splash, or use a water spray. Never store stones in water. Never dry near heat.
Disclaimer. For international markets, Naniwa uses names "sharpening stone" for Super Stones and "professional stone" for Chosera. Such generic names are confusing. We use more recognizable names "Super Stone" and "Chosera".
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.
