Product detailed description

King Deluxe Water Whetstone S-3 JIS #6000 with Base

The King Deluxe Sharpening Stone S‑3 #6000 from the Japanese brand King (Matsunaga Stone Co.) is designed for final polishing and ultra-fine honing of knives, chisels, scrapers, and other precision tools. Its JIS #6000 grit allows you to achieve a mirror-smooth surface, which significantly improves not only the sharpness but also the overall aesthetics of the blade. The grinding surface has a very fine and stable abrasive structure that effectively removes micro-scratches and creates a perfectly smooth surface in the final stage of sharpening. The stone is made of ultra-fine aluminium oxide (corundum), which guarantees high precision and even stock removal. Thanks to the synthetic binder, the stone has a long service life, low porosity and the same sharpening performance throughout its use. The package includes a plastic stand that ensures the stability of the stone during work and safe contact with the work surface – the stone does not move during sharpening, making work more comfortable and efficient.

Before use, the stone must be soaked for approximately 3 minutes until the surface is evenly moist. It does not need to be soaked for a long time – after a short swelling, it is ready for immediate use.

How to Properly Sharpen Knives on a KING Sharpening Stone

1. Namočení kamene
Before sharpening, submerge the stone in water for at least a few minutes to ensure it is fully saturated. Throughout the entire process, the stone should remain damp – re-wet it whenever it starts to dry out.

2. Zajištění stability
Place the stone on a flat and stable surface. To prevent slipping, you can place it on a damp cloth, rubber mat, or paper towel.

3. Nastavení úhlu ostření
Hold the knife at an angle of approximately 15–20 degrees to the surface of the stone. This angle is ideal for most kitchen knives and ensures optimal sharpness and edge durability.

4. Sharpening itself

For single-bevel knives (e.g., some Japanese models): Sharpen mostly on one side – dedicate 90% of the time to the main side and 10% to the opposite side.

For double-bevel knives: Sharpen evenly on both sides of the blade to maintain symmetry and sharpness.

5. Odstranění otřepů
After sharpening, fine burrs may form on the edge of the blade. To remove them, hold the knife perpendicular to the stone and lightly run the entire length of the edge several times – alternating between one side and the other.

✅ Whetstone maintenance

After sharpening, rinse the stone with clean water to remove any metal residue and allow it to air dry completely (not on a radiator).

If depressions or unevenness develop on the stone over time, level them using a flattening (flattening) stone, to maintain a smooth and even surface for future sharpening.
