Thread: Diamond Brand Chinese Combination Sharpening Stone

What kind of sharpening stone is this?



It is extremely cheap, 1,5 euro.
It has two different combinations. One looks like 4000grint and the other side 8000grint, but this is only my speculation as the box describes nothing.
Dimensions: 200x50x25mm
Aluminium Oxide is written.


Is this a water stone or an oil stone?
Can I use it to sharpen my razor?

Does anybody know this stone?

Thank you.

If I'm not mistaken aluminum oxide might be a bit coarse for a fine razor hone ? I'll defer to others who may be better informed than I am though.

It works with oil or with water ?

Hard to say without feeling it, but at that price and from the look of it I'd say it's more like a 200/400 stone. I wouldn't put a razor on it until I had a really knowledgeable person check it out, if I were you.

You might try an old knife on the smooth side. If it doesn't scratch up much, I'm wrong and you could be good to go.

From the cover you can tell it's an oil stone.
Probably coarse/medum combination stone.
This kind of cheap stone usually used for housekeeper and didn't tell the grade level.
I don't think your razor can use this only. You need more than super fine stone to have your razor shave ready.

I have already ordered a 12,000 chinese waterstone.
Would that be ok, or an intermedian stone (ex. 8,000) is necessary?

Looks really coarse to me. Like really really coarse. I have a similar stone that I bought a long long time ago. Even a 1000 grit stone feels really smooth to the touch, so if that stone doesn't feel really smooth to your finger, it's way too coarse.

Most aluminum oxides are coarse. That hone, if you troll Google hard enough, will show you the grit is 220 on the FINE side for that exact hone. The other side is 120 or 150.

Too coarse unless you are working chips out.

Thank you guys, thank you very much.

If you're just touching up edges that have started to pull, an 8k and 12k should be plenty.

For full honing or restoration, the commonest stone collection seems to be

1) 325-grit diamond hone w/continuous diamond surface, for lapping
(get DMT brand, to be sure it's flat)
2) 1000-grit diamond or water hone, for bevel setting
3) Norton 4k/8k or Naniwa 3k/8k combo for sharpening
4) Finisher of your choice, like your 12k Chinese waterstone.

You can find more mentions of your 12k stone by searching the threads for "C12k" or "PHIG" (People's Hone of Indeterminate Grit).

If you want to try to do all your honing on a single stone, look into Belgian coticules and the unicot method. There's a lot more to learn about them, but they're very flexible honers. Since you've got a finisher already, you'd want to shop for a faster coticule. One fast coticule would do the work of your 1k through 8k stones.

I agree with the other posters--keep your razor away from the stone in your picture. It looks like something for garden tools.
