Sharpening with a Coticule:

The sharpening always uses water. All that is required is to wet the Coticule surface; there is no need to immerse the stone. During sharpening, garnets are released from the Coticule surface. The more garnets are released, the more abrasive the grinding compound becomes.

A frequently-used method for increasing abrasiveness is to use a rubbing stone (= Bout n° 1) to produce a grinding compound with a high garnet content on the Coticule surface. This is done by rubbing the Coticule surface of the rubbing stone over the Coticule surface of the whetstone. The milky white grinding compound does not take long to appear.

For the fine honing, the grinding compound is diluted in a number of stages with a small amount of water until finally there is only water on the surface.

This method, combined with the versatility of the Coticule, means that only one whetstone is needed for the entire sharpening process.

Tips:

Coticule is a non-porous stone and cannot become clogged.

Use only water when sharpening, not oil. Oil is only used with porous stones to prevent iron particles remaining stuck in the pores.

Flattening: Place a piece of sandpaper on a flat surface. Put some water on it and rub the stone flat. use sandpaper with grain +/- 80 to 100 micron.

Working life of stone: The working life depends on the use. The more intensive the use, the faster the stone will be worn away. Generally speaking, our whetstones last 20 years in normal use. 

 

Sharpening with a BBW:

The sharpening always uses water. All that is required is to wet the BBW surface; there is no need to immerse the stone. During the sharpening, garnets are released from the BBW surface. The more garnets are released, the more abrasive the grinding compound becomes.

A frequently-used method for increasing abrasiveness is to use a rubbing stone to produce a grinding compound with a high garnet content on the whetstone surface. This is done by rubbing the rubbing stone over the surface of the whetstone. The bluish purple grinding compound does not take long to appear.

For the fine honing, the grinding compound is diluted in a number of stages with a small amount of water until finally there is only water on the surface.

This method, combined with the versatility of the BBW, means that only one whetstone is needed for the entire sharpening process.

Tips:

BBW is a non-porous stone and cannot become clogged.

Use only water when sharpening, not oil. Oil is only used with porous stones to prevent iron particles remaining stuck in the pores.
