Detailed information

Product detailed description


Diamond sharpening stone, which can be used to sharpen hard metals, ceramic knives, or sintered carbides, which is not possible with regular sharpening stones. It is more resistant to wear than common 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.

Features of the diamond stone:

✅ Double JIS grit: #400 and #1000
✅ Double-sided diamond stone
✅ For dull blades (#400) and regular sharpening (#1000)
✅ Anti-slip pad included in the package
✅ For materials unsuitable for regular water stones

Which grit to choose?

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


  • #120 to #600 JIS: for dull 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
