Belgian Coticule Whetstones are used for super finish sharpening on KME or Hapstone knife sharpeners.
Yellow Coticule Whetstone is mined in the Ardennes mountains in Belgium. Coticule is ultra-fine natural stone with a high garnet content. Coticule is one of the most well-known whetstones in the world.
Coticule stones are universal, and can be used to sharpen knives of any steel.
The stone can be either pure coticule or coticule + satellite combination stone glued together. Satellite stone is used to make the product rigid and thick enough.
Coticule Whetstones should be used with water. All that is required is to wet the Coticule surface. There is no need to immerse the stone. During the sharpening, slurry with garnets are released from the Coticule surface. The more garnets are released, the more abrasive the grinding compound becomes. Try to keep slurry on stone surface.
Coticule stones do not have any minor defects. Coticule stones always have a color pattern; this is not a defect.
Coticule stone does not require any preparations. It is naturally lapped to ultra-fine grit.
Grit terminology is not applicable to natural sharpening stones. The behavior of a natural stone depends on its density and how good it was lapped. However, experts estimate Coticule at least 10000 JIS.
We use either inexpensive hard slate or flawed jasper as sattelite stone. They are abrasive but we don't recommend to use the satellite stone for sharpening.
