Okudo Karasu

[livio]

Hello, I get this stone is a Okudo Karasu, hard stone, what is the best way to get the most of this stone. I try it with slurry , after 12K , the edge is the same, with water it improve a 12k, shaving is better, but no more HHT. Please advise on the best method.

How do you make your slurry?

I have a piece of translucent ark, hardest stone know to me.

Ok, check that you don't scratch up bigger particles but instead rub it gently to get a fine even slurry.
Hard to know how your stone is without trying it, I'll put on some coffee if you got time to bring it over!

Thank you, I would love some coffee, and I would love to visit Sweden, the stone is lapped up to 2k, and the ark don't scratch the surface. I will use it more without slurry,
to get an iddea what the stone can do. Even without slurry , in 2 min, the water became darker, maybe is the karasu strata. Why I can get HHT if the edge is better?

I've noticed the "HHT" phenomenon too off one or two of my Jnats (except for me it is not HHT, it is the arm hair waft). Straight off the stone, nothing. But after a very good stropping I do get good hair tests. I always thought it had something to do with the particles floating around in the water and kind of banging into the edge - I think they call it slurry dulling or something. But the particles are small and as I said a good stropping seems to remove any issue. What happens to yours after you strop it?

If you can afford it I would suggest that a good quality diamond plate in the 1K region is an excellent way to both make slurry on a hard Jnat and keep it lapped and clean. I use an Atoma 1.2K diamond plate for this purpose on all my harder Jnats. Yes, they cost more initially but they last a very long time and are of excellent quality for the money.

Good luck.

James.
