Sungari Whetstones are used for the finish or pre-finish sharpening on KME or Hapstone knife sharpeners.
Sungari is mined in the Sungari river in China. Sungari is extra-fine natural stone with estimated grit approximately 4000-5000 JIS.
Sungari stones are universal and can be used to sharpen knives of any steel.
Sungari is preliminarily lapped and does not require lapping after purchase. Sungari sharpening stones should be used with a honing oil or water as a lubricant. The stone does not absorb oil or water. When using honing oil, put a small amount (1-2 drops) on the stone’s surface and spread it evenly over the stone with a finger. Remove the used lubricant with a paper towel.
Sungari can be many different colors. May have slight natural imperfections and a color pattern; this is not a defect. Sungari stones usually have manganese lines which look like cracks; this is not cracks.
Advantages of aluminum blanks
Stones mounted on aluminum blanks are thicker than stock KME stones. We recommend using the thickness compensator if you use stones of different thickness.
