J-Nat club

Like Steve said some Jnat guys know tell tell signs of mine provenance. If you read on So Yamashita's site he specifically refers to being able to tell certain characteristics of Okudo for example but he doesn't go into details. From an old blog Jim Rion wrote I remember reading his trip to visit Hatanaka- San and he took a yellow stone with him which he thought was Nakayama. Hatanaka - San said nope, it isn't.
The rest of us rely on what the sellers tell us and hope for the best.
Off course everybody will say mines don't matter, well they don't if the stone delivers and does it's job but at the same time certain mines command higher prices. A grey shobu is cheaper than a same size grey Nakayama.

So these are various kiita base colors I have some have karasu, Iromono and other patterns that change it a bit, but I would call all the base color kiita to different degrees. I took pics at different angles and lightning the best I could to try and show how that can effect the look a bit. These are all dry pics.

I sure cant argue what is Kiita and what isnt. But a couple of those look a bit dark. Just making the comment. Nice group of stones!

Thanks.

The Iromono front middle left is a good example of how dry doesn’t look much kiita but wet shows it better.

Randomly what would you guys recommend for slurry and lapping. A dmt or atoma?

I use Atoma.

What grit. Was looking at the 1200

I use w/d sandpaper on a piece of plate glass. I don’t like the scratches that even the 1200 Atoma leaves. A mellow DMT 325 works well but sticks to the stone badly.

If you use a diamond plate, don’t let the slurry get sticky, it can bork the plate. Under running water is best, but in any case just make sure the slurry doesn't thicken up when lapping with a diamond plate.

Thanks for the tip. Would never of thought of that.

1200 might get stripped by a very hard stone, mine did.
I use Atoma 400 for lapping now and for general maintenance a very well worn DMT 325.
