Detailed information

Product detailed description


Diamond sharpening stone, which can be used to sharpen hard metals, ceramic knives, or sintered carbide, which is not possible with ordinary sharpening stones. It is more resistant to wear than standard Japanese water stones and does not require surface adjustment of the sharpening stone. It is a double-sided stone with a dual surface. Do not use oil, as it could damage the surface - if the stone becomes clogged, use a brush and wash with soap. After washing with water, wipe off the water and thoroughly dry before storing.

Diamond stone features:

✅ Double JIS grit: #150 and #600
✅ Double-sided diamond stone
✅ For blunt blades, a stone with high coarseness
✅ Non-slip pad included in the package
✅ For materials that are unsuitable for regular water stones

Which coarseness to choose?

For sharpening really blunt or uneven blades, use stones with a low JIS number (Japanese classification for grit). The lower the number, the greater the coarseness of the stone. Stones with a high JIS number are intended for final and fine sharpening or smoothing.


  • #120 to #600 JIS: for blunt and uneven blades
  • #700 to #2000 JIS: for normal sharpening
  • #3000 to #5000 JIS: for fine sharpening of quality blades
  • #6000+ JIS: extremely fine stones for smoothing or removing scratches
