The King KW65 1000/6000 is a good first whetstone and an easy recommendation. It's made in Osaka by Matsunaga Stone Co., the 1000 side is soft and forgiving while you learn, and the 6000 side gives a fine finish. Two things to know before buying: only the 1000 side gets soaked (about 2 minutes), and a soft stone dishes quickly, so plan on flattening it. If you'd rather never soak or flatten, the Shapton Kuromaku #1000 is the better buy.

How we reviewed it
This is a spec review, not a hands-on test. We compared every King stone in Amazon's results on October 13, 2026 (three versions of the KW65 plus the KDS and PB-series combinations) using their listings. We read the instructions published by the Japanese knife retailers that sell King stones (Korin, Seisuke, SharpEdge, MyGoodKnife and Japanese Taste) and compared King with Shapton and Suehiro using The Chef Dojo's descriptions and listing data. How we research.
What the KW65 is
| Spec | KW65 | Source |
|---|---|---|
| Grits | 1000 (dark side) / 6000 (light side) | Korin |
| Size | 185 x 63 x 25 mm; the Amazon listing rounds this to 8 x 2.5 x 1 in | MyGoodKnife; Amazon |
| Base | Plastic stand included | Amazon, MyGoodKnife |
| Lubricant | Water only | All retailers |
| Maker | Matsunaga Stone Co. (King brand), Osaka, founded 1948 | Japanese Taste, Korin |
| Owner ratings | 7,517, 4.6 stars | Amazon, October 13, 2026 |
The listing's dimensions and the retailer's don't quite agree. The 185 mm length is the useful number: shorter than a 210 mm Shapton or Naniwa, which you'll notice on a 10-inch chef's knife.
Soaking: the instruction everyone gets wrong
Retailers give two different soaking instructions for King stones, and both are right for different stones. The combination stone isn't the same as a single-grit stone:
| King stone | How to wet it | Source |
|---|---|---|
| KW65 and other 1000/6000 combinations | Soak the 1000 side about 2 minutes; splash the 6000 | Korin, Seisuke |
| Single medium stones (800, 1000) | Soak until bubbles stop rising | Japanese Taste; King 800 listing ("requires submersion") |
| Finishing stones (3000+) | Don't soak; splash and keep wet | Korin, Seisuke |
Keep the surface wet while you sharpen. Splash more water on as it dries. When you're done, rinse off the slurry and let the stone dry completely before it goes back in its box. Korin and Seisuke both warn that a stone boxed damp grows mold.
Using it: the short version
- Soak the 1000 side as above and set the stone on its base on a towel, dark side up.
- Sharpen on the 1000 at your knife's angle until you raise a burr along the whole edge, then do the other side.
- Flip the stone to the 6000 and splash it. Repeat with lighter strokes to refine the edge and shrink the burr.
- Finish with a few alternating light strokes. Rinse the stone and let everything dry.
The 1000 side does nearly all the work. Our is a 1000 grit whetstone enough guide explains why, and how to use a whetstone covers the stroke in detail.
What it does well, and its one real drawback
A soft stone gives you feedback. You feel and hear the steel bite, slurry builds quickly, and small mistakes in angle don't punish you the way a hard stone does. The Chef Dojo calls King stones very soft and more forgiving to use, which is why so many guides start beginners on one. SharpEdge, which sells King stones, notes that they're baked rather than only pressed, which it says reduces wear compared with its own economy stones.
The drawback comes with the softness. The Chef Dojo points out that King stones wear down faster than harder brands. A dished stone rounds your edges, so a KW65 needs flattening every few sessions. Budget for a flattening stone or a diamond lapping plate made for flattening from the start (DMT's FAQ says its ordinary diamond sharpeners aren't meant for flattening waterstones). Our guide to flattening a whetstone shows the pencil-grid method.
Is 1000 to 6000 too big a jump?
It's a big step, and you'll feel it. The 6000 has to polish out every scratch the 1000 left, and on a soft finishing stone that takes a fair number of light strokes. Three things make it easier. Finish the 1000 stage with lighter strokes so the scratches are shallow. Use a nagura on the 6000 to raise slurry, which speeds it up. Or choose a gentler pair: Suehiro's compact 1000/3000 splits the difference, and our grit progression chart shows other combinations.
King stones for chisels and plane irons
King isn't only a kitchen brand. Japanese Taste describes the King Deluxe 800 as suited to plane blades, sickles, chisels and kitchen knives, and the PB series is sold for carbon steel. Woodworking tools are wide and flat, so they wear a groove into a soft stone faster than knives do; flatten more often if you use your King for chisels. Our guide to sharpening a chisel covers the honing guide and back-flattening steps.

King Whetstone Starter Set
The same 1000/6000 stone plus a knife angle holder and a wiping cloth. The listing describes the holder as having two ceramic protective rods with a plastic base. If holding an angle by eye worries you, a holder is a reasonable crutch while you learn.

Why it stands out
- Angle holder included
- Made in Japan per the listing
Think twice if

Why it stands out
- Made in Japan per the listing
- No plastic base to store
Think twice if
- You need a base; get the KW65
King PB-04 (800/6000)
King's carbon-steel combination, with a slightly coarser 800 for faster sharpening and the same 6000 finisher. The listing says to submerge it before use.
- Grits800 / 6000
- Size185 x 63 x 25 mm
- Baseplastic
- Wettingsubmerge before use (listing)
Why it stands out
- Faster 800 side
Think twice if

- Grits220 / 800
- Includesplastic holder, clear case
Why it stands out
- Handles damage a 1000 can't
Think twice if
- Your knives only need routine sharpening
There's also a single King 6000 finishing stone (made in Japan, per the listing) and a pocket-size King 800 at 129 by 39 mm, which is too small for kitchen knives but handy for tools.
King vs Shapton vs Suehiro vs a generic 1000/6000

| Owner ratings | 7,517 | 4,535 | 642 | 25,709 |

Who should skip the King
- Anyone who won't flatten a stone. A dished King does more harm than good.
- People who sharpen in a hurry. The soak, small as it is, and the drying afterward add time. A splash-and-go Shapton or a diamond plate is ready immediately.
- Owners of very long knives, who'll find 185 mm short.
Our verdict
Buy the King KW65 as your first whetstone, add a flattener, and soak only the dark side. Get the starter set if you want the angle holder. When you outgrow it, the usual next step is a harder 1000 that holds its shape, and that's where Shapton comes in. For complete kits from other makers, see the best whetstone sets for beginners.
