Dan's Whetstone Black Arkansas sharpening stones are used for finish sharpening knives on KME or Hapstone knife sharpeners. Arkansas stones are made of novaculite, a naturally abrasive material of high density.
Arkansas stones are mined in the Ouachita Mountains in the state of Arkansas in the United States. Arkansas stones consist of silica, but unlike synthetic abrasives, do not consist of individual abrasive grains of the same size. Arkansas quartz structure consists of fused crystal grains of different sizes.
Dan's Whetstone offers Arkansas stones of the following types:
- Soft - medium grit range
- Hard - fine grit range for pre-finish sharpening
- Translucent - ultra-fine grit range for finish sharpening and honing
- Black - ultra-fine grit range for finish sharpening and honing
Arkansas stones should be used with oil as a lubricant (refined olive oil, oleic aсid, or Dan's honing oil).
Arkansas stones usually have moderate variations of shade and color. This is normal for natural stones and not treated as a defect.
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.
