Thread: Buying Chinese 12K in Europe?

Guys I am thinking of buying this guanxi
hone. I sharpen plane blades and chisels
and use 800,3000 and 8000 naniwa ss.

I find the naniwas very soft and sometimes
the blade gouges in the stone.

I am thinking of buying a very hard asagi
in the future, but in the meantime I would
like to try this very hard chinese hone. I
was thinking of using this hone instead of the
naniwa 8000.

I would try to solve the gap between the #3000
naniwa SS and 12000(some say lower, others higher)
with a nagura slurry and then finish with only water or
slurry of the guanxi itself. Pretty sure this would work.

Anybody know where I can buy this hone in Europe?
I am interested in the bigger size with a slurry stone.

Are these stone with lots of inclusions, cracks? The price
is very low compared to coticules,eschers and jnats. Is it
possible to get a stone without lines/cracks, basically flawless?

If anybody is selling this hone in the 8 by 2.5 in Europe,
let me know?

Thanks

If you scroll down on the link, you will see it for sale Razor Hones

A guy from Poland sells these stones in ebay.

I would recommend a Shapton 8.000 to you!
Shaptons cannot be gauged, and are great for bigger knives.
You could even jump from Naniwa 3k to Shapton 12k!
Much quicker and more consistant than the C12k.

On the other hand, I bought my C12k from Poland and am very pleased with the transaction

I bought my C12k from that Polish guy, it came lapped and ready for sharpening fun.

Indeed it does come flat, but the performance of the C12k is greatly improved by polishing the surface.
This is hard work! You buy a stone for 25€ and have to work on it for like 60€ (in life-time).

I recommand either lapping film for the final polish, or rubbing the C12k under running water against some very hard and quite fine stone.
I found the BBW works miracles on the C12k. I have small (credit card size) BBW that I ran across the C12k initially for about an hour.
This brought the C12k to an extremely smooth and shiny surface. As smooth as my Shapton 30k!
That´s where it performs best. A little bit like the Spyderco, I figure.
The polish of the surface has an impact on the quality of the edge it gives

But of course this makes for a slow, slow stone

that Polish guy

sounds like he´s the polishing-man

Thanks guys for the responses.

I had seen the polish guy selling the stone, but his stones are
too small for my purpose. I will ask him if he also sells the bigger
stones, but I am guessing not.

Good advices about smoothing the C12. Have you tried 30.000
loose grit on floatglass?

Thanks for the link Scipio.

Lessleeming I will think about the shapton, but its a synthetic stone,
I like naturals more.

Hi Sharpman,

the ebay seller open_razor definitely sells bigger C12k. Just recently I bought a 200x75mm C12k, the biggest stone in my repertoir.
I paid 28€ shipped to Germany. Insane!

What do you mean with 30k loose grit on glass? You mean for honing?
In the grit range beyond 8.000 JIS everything gets very confusing. What kind of powder are you referring to?
(What kind of abrasive and what is the actual grit size?)

What I tried (for kitchen knives, anyway) is a spritz of 0.5µm diamond on the C12k,
or a 0,5µm Al2O3 powder on the C12k. Both works acceptably fine and a lot quicker than the C12k alone.
The C12k is quite a good plattform for any kind of slurry. It´s similar to glass in many ways

If you´re into naturals and you want to jump from Naniwa Super 3.000,
you might want to check with a repuable seller of japanese naturals and ask for tiny stones usable as nagura.
I use my C12k this way:

I set a bevel on my Chosera 1.000. Then I use a slurry I made with a ~5-6.000 Suita on my C12k.
I rinse the Chinese, and repeat the step with a lighter slurry.
Then I switch to another nagure, around 8.000.
Afterwards I create a very fine Ohira slurry on my Chinese.
I finish with a couple of light strokes on the C12k alone.
It´s not quite enough for shaving that way (for me, anyway)
but one hell of a finish for kitchen knives and such.

But the slurry stones can be quite expensive (as expensive as the C12k itself, I guess).
But the one stone honing is quite nice, and almost all natural

what´s your budget?

Hi Lessleman,

I meant #30.000 grit loose grit on floatglass and then moving the stone over it
to really smoothen the stone, of course after the stone has been flattened
completely.

The 30.000 loose grit I have seen was made from silicone carbide. It was being
sold in small packages of 100 grams or so.

Yes, exactly that is what I was thinking to do, just use naguras on the stone
after having set the bevel. Where did you get the 0.5 micron aluox powder?
I think that would be a good way of using the chinese hone since it is so slow, just
use very fine loose grit on it as you did.

I will ask the ebay seller. That is a good price you got it including shipping! How
was the surface of the stone? Lots of inclusion, small cracks, lines?

Sharpman

He's currently selling 8x3" stones + slurry stones (360262320717) but I've seen even bigger ones in his store before, 10x3" maybe. There's also another seller that sells 16x6x2" Guangxis iirc. You can cut that up any way you like it.

I haven't seen any reports on inclusions in Guangxis, they also don't have cracks. Some Guangxis do have lines and these stones may actually be the best Guangxi wise.
