Thread: Ozuku Jnat lapping with DMT 325?

I have flattened a few very hard jnats with my dmt, I didn't encounter any problems. After a few uses with the slurry stone, it was as smooth as it could be. I didn't find any performane differences between the two, but I didn't even bother to find out if there is a difference. If you don't push too hard, it won't leave too big scratches in the stone, it is too hard to really dig in with a lot of water and almost no pressure.

Just out of curiosity: is it necessary to flatten your ohzuku or is it still in good shape?

No, not necessary. I just like to obsess about technique. Perhaps I will never hone it. It kind of makes my stomach squirm at the thought of taking a diamond plate to this stone. On the other hand, it is just a rock that we've somehow elevated to mythical status. And then I convince myself that the edge is somehow smoother than what I get on a manmade stone.

On my Japanese natural stones I use my Atoma 400 exclusively for both lapping and raising a slurry. On all of my synthetic stones, Naniwa's, etc. I use my DMT 325.

I've been using a dmt 325, then a BBW, then my coti, gives it a mirror finish on it if you look at it at a 5-10 degree angle
