KING grinding stones
KING sharpening stones – Japanese care for perfectly sharp knives
KING sharpening stones are among the most popular Japanese water stones for hand-sharpening kitchen knives. They are suitable for routine blade maintenance, restoring dull knives, and fine final polishing.
Thanks to a wide range of grit sizes, you can easily choose a stone for every stage of sharpening – from rough edge alignment through universal sharpening to fine finishing and polishing of the blade.

Choose a stone by grit
Coarse stones #220–#400
Suitable for very dull or damaged knives, edge repair, and rapid material removal. Use them when regular sharpening isn’t enough.
Medium grit #800–#1200
A versatile choice for regular sharpening of kitchen knives. Restores the edge, improves cutting performance, and prepares the blade for a finer finish.
Fine stones #4000–#6000
Used for final smoothing and polishing the edge. They are ideal for Japanese knives, precise slicing, and a smooth, clean cut.
Combined Stones
A practical solution with two grits in one block. Great for home sharpening, saving space, and a starter kit.

How to properly use the KING water-grinding stone?
1. Prepare the stone
Soak the water stone before sharpening according to the recommendations for the specific model. Keep the surface of the stone moist while working.
2. Maintain the correct angle
Kitchen knives are most often sharpened at an angle of approximately 15–20°. A steady angle is more important than force.
3. Start with a coarser grit
Start with a coarser stone depending on the condition of the blade, then move on to a finer grit for smoothing and polishing.
4. Clean the stone after use
After sharpening, rinse the stone, let it air dry, and store it away from prolonged moisture.
