This novaculite sharpening stone is used as the last stage of sharpening your knife or tool to help bring on a more refined / polished edge. This stone is also called ‘surgical black’ (for its past use in the medical and dental community to sharpen instruments). Due to its density this stone can be a slower cutter than synthetic whetstones. Best used only once a sharp edge has been produced by the courser stones / grits.
The extra fine black can be used not only as the final stage of sharpening after the medium / soft and hard / fine novaculite stones, but can also be used in a progression with other stones (natural / synthetic). Could also be used after the coticule.
Tip! When using whetstones, swarf (metal particles) will build up on the surface. It will begin to get a black appearance (as pictured, although you won’t see this one the black stone, so a regular cleaning routine is best).
This will happen to varying degrees depending on the stone used (some are more prone than others). Although you don’t get a large amount on Translucent (or Black) Arkansas stones, one easy way to clean this off when it does appear is to use a coticule slurry stone
The slurry stone will clean this off easily, but won’t effect the grit rating to any real degree (you may smooth out the surface of a coarser stone too much when using a slurry stone that is much finer). But on a Translucent or Black Arkansas, no problem, as all three share a similar range.
Also, as the coticule is a little coarser than either the Black or Translucent, this will also help recondition the surface if you find the Translucent / Black has smoothed out overtime. After a few rubs over the surface (with water), you will find the Arkansas stones will have a very slight bite in them again, not to mention being clean again. I use this method often! Recommended for both the Translucent and Black stones only.
For cleaning Washita, Soft or Hard Arkansas it is best to use a scrubbing brush and soapy water.
