Why this stone
The stone, and what it is for.

Key features:
- Restore a dull edge to a sharp one and put a mirror polish on the back and bevel
- Made up of abrasive particles held together in a soft bonding compound
- Consists of aluminium oxide, carbide and nitride particles fused together
- Soft bonding clay releases the abrasives very easily when the stone is soaked
- #800 grit measures (L) 8″ x (W) 2 5/8″ x (H) 1 1/4″
- Made in Japan
The King #800 Japanese Sharpening Stone
With its medium 800 grit, this stone removes moderate amounts of material to restore a dull edge before you refine it on a finer stone. Wet the stone, then draw the blade across it at a consistent angle and pressure with a steady, controlled motion. Regular sharpening on it keeps your blades cutting cleanly and extends their life.
Japanese Whetstones
Unlike other synthetic sharpening stones which consist of a single abrading agent, these Japanese water stones consist of aluminium oxide, carbide and nitride particles fused together. This blend is mixed with a clay-like bonder and baked at high temperatures to form the sharpening stone. The resulting stone is soft but sharpens very quickly. The soft bonding clay allows the abrasive particles to release very easily when the stone is soaked in water, giving the user a constant supply of fresh cutting surfaces with which to grind, sharpen and hone their tools.
Now favoured by many professionals and occasional users over natural stones, when you buy a synthetic Japanese sharpening stone you are guaranteed a stone with a uniform grit size that produces consistent, high-quality results and does not vary in quality from stone to stone.

Who makes it
King. The stones Japanese chefs trust.
King has been making Japanese water stones since the 1940s. Their combination stones are what serious cooks and sushi chefs reach for when they want one stone that does everything — the grit is denser and faster-cutting than consumer-line stones, and it lasts noticeably longer.
This isn't a small-workshop relationship. King is a proper company with a long track record. We stock them because they are what a knife like ours actually needs.
Care, briefly
Stones don't need much. Three rules.
01.
Soak for fifteen minutes.
Before each sharpening, submerge the stone in water for fifteen minutes. Bubbles rise as it absorbs water — take it out when they stop.
02.
Use the base.
Always seat the stone in its base before sharpening. A slipping stone is the most common way home cooks cut themselves.
03.
Flatten it when it dishes.
After a year or two the surface dishes slightly. Flatten it with a flattening stone, or wet-and-dry paper on glass. Or send it back to us and we’ll do it — you cover shipping both ways.
What you receive
In the box.
- The stone you chose, in its grit, ready to soak and use.
- A non-slip base where the stone ships with one.
- A care card with the soak, the base and the flattening note, and a link to Knife School.

Reviews.
Good quality sharpening stone that does what it promises. I use it to maintain my Japanese knives every few weeks. The grit is consistent and it doesn’t dish out too quickly. Solid purchase for the price.
Excellent starter stone. The #800 grit is perfect for regular maintenance sharpening. Creates a nice slurry quickly and gives a consistent edge. Soaks in about 10 minutes and stays wet throughout the session.
