Thread: Woodcraft Chinese 12k stone

Anothe option is to buy a C12 from open_razor on ebay that's already lapped & chamfered. And also comes with a slurry stone.

I too like to see/feel something in person before I buy it. If you get it from a seller on ebay, just make sure you can return/exchange it if there's something about it you don't like.

If you find one that comes with a slurry stone, get it. The slurry will save you a bunch of laps, since the c12k stones are very slow cutters, but they do indeed put a heck of a polished finish on a razor IME

I have a really small carborundum hone that I use to raise a slurry on this stone, works like a charm

I didn't like myc12k at all. When you get it, your best bet is to go outside and lap it on concrete and then hitthe sandpaper or DMT. I did mine in 10 minutes this way.

After it was lapped, did you like the results? I've heard bad things about lapping, but good things about the results.

I love mine, puts a great polishing on the edge.

I got mine Chinese yesterday. I ordered it from The Invieble Edge. It was very fast delivery, I ordered it at friday and I got it at tuesday.

I am now lapping it. It feels quite different than my Naniwas, they are lot of softer than a Chinese. I have read somewhere in the SRP that it is very hard stone, and lapping takes a little more time than a softer stones.

First I started with 400 grit waterpaper. At the begin there was coming slurry a little. Then it feels like there was happening nothing. Then I tried 320 grit and I am not sure if I must go even coarser. There are still a minimun natural prints on ist surface in the margin of the stone. I can feel those with my finger, but they are minimal as I mentioned. In the most part of stone surface is like a mirror. What about those prints, are there any change to get good honing result without removing those prints?

What you think about the lapping grits with Chinese? And how long it would take approximately. I lapped my three Naniwas in the one evening. Now I have lapped my Chinese one evening and I am still not there.

I think it's a great value. The finish I get is as good as any stone I've tried (not that I'm a master or anything). For $20, it's not a big gamble to give it a shot.

I just received my C12k from Woodcraft this morning. Out of the box I don't think you'll want to put your razor on it. Mine had tooling marks from to stone saw on it so I lapped it right away. I lapped it on a piece of machined aluminum billet starting with 220 grit and proceeding through 400 and 600. It took about 90 min. to get it like I want it. The question I have at this point is 600 grit fine enough? I also put a radius on the corners and edges.

I'm hoping to use it to simply polish and maintain my razor's edge. While I have lots of experience at sharpening all sorts of tools, I've found out in the last six weeks that maintaining a shave ready razor is another kettle of fish.
