The **Work Sharp Coarse Diamond Kit Professional Precision Adjust** consists of two replacement sharpening stones for the Work Sharp Professional Precision Adjust sharpening system. A must-have set if your old sharpening stones are used up, damaged or lost. The coarse sharpening stone of 320 grit will fix a damaged edge or change the sharpening angle if necessary. The 400-grit sharpening stone will make your relatively blunt knives sharp again. 

The end result of these sharpening stones is still pretty rough. That is why we recommend using a finer sharpening stone after using this coarse stone to make the knife razor-sharp again. Please note: diamond sharpening stones need to be 'pre-sharpened'. This means that the stone will seem coarser at first use than it actually is. After sharpening a few knives this effect will disappear, and the stone will reach its optimal level of effect.

## Replacing a Professional Precision Adjust sharpening stone

The sharpening stone holder is magnetic, making it easy to attach a sharpening stone to the holder. You can quickly and easily select the right sharpening stone without having to remove the holder from the system.
