Sharpen blunt tools with this Yasunari sharpening stone. The 240 grit is one of the coarsest in our range and is particularly suitable for restoring blunt or damaged tools. You can then switch to 800 grit for further sharpening.
The whetstone is used in combination with water, which is why the sanding process is also referred to as "honing". Sanding dust and residue can be easily rinsed off. Use the entire surface of the whetstone to avoid gouging. If necessary, the grindstone can be leveled with a leveling stone after some time.
The scope of delivery includes a rubber stand that stabilizes the stone and prevents it from slipping.
For optimum stability, we recommend a bamboo holder (9010080) or a metal holder (9010082).
Special attachments are available for knives (9010084) and chisels (9010086) to ensure that the correct sharpening angle is always maintained.
Yasunari whetstones are available in three grinding grades;
- Coarse stones: These normally have a grit of less than 1000 and are best for repairing very blunt tools and broken edges. The greater the damage, the coarser the grit required.
- Medium stones: These are between grit 1000 and grit 5000. We recommend these for regular maintenance of tools that have lost their sharpness.
- Polishing stone: These stones are equipped with very fine grits from 5000. They sharpen more slowly than coarser stones, but produce an exceptionally sharp edge. Use a polishing stone to refine and polish the edge of your blade.
