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.
