The first two kanji are: 大突 = ozuku (mine)A bit of a strange one… Ozuku suita. Which suita? No idea. Dirt cheap, no description, just theoretical pedigree - and I do like the suita I have very much. I’ve never encountered in my brief jnat history an ozuku suita. I do have a random koppa from the same mine, and it’s insanely hard and slow.

Pretty vanilla looking, two toned separated by what looks like a serious crack, with maybe some light grey suminagashi if you have a strong imagination. The back shows the same mottling and some color, although I don’t expect it to ever show. I’m very curious as to how it behaves. I would like to think I’m at the point where I can ballpark the stones’ attributes.. if all else fails, a head to head with the other stones should be telling. View attachment 184354
Edit: does anyone know what that says? I got the first and last kanji, but that’s about it. I fear some serious lapping is in order and those stamps are going to be history.
Starting on concrete is probably the best way to go about the rough work. I'd probably add some loose SiC to the mix, but iirc that's not very easy/economical to come by for you. I'd probably "finish" the surface using a harder, finer, stone if you had one, but you can get away with just doing some thinning work on it post rough grind.Got this lump of natsuya today, spent ages grinding out the saw marks but I must say it looks pretty nice! My first real sized jnat, I got my first small jnat less than two months ago and have since been gathering koppas since. This one seems a bit harder and finer than other examples I have seen, it doesn't produce much mud and leaves a pretty good polish on the blade with decent contrast. I have an aizu coming my way shortly and probably another natsuya so it will be interesting to see the difference between the two.View attachment 188436View attachment 188437

Also does anyone have any suggestions on how to grind down the rough saw marks quickly? I was using a concrete block but it seemed about the same speed as my atoma 400. I also had a go with a belt sander but it clogged up the belt since it was wet from already grinding down on concrete. Also not having stone dust everywhere would be nice
P80 coarse silicone carbide sandpaper works like a charm. Kind of pricey though.Got this lump of natsuya today, spent ages grinding out the saw marks but I must say it looks pretty nice!

Just got my first. It was gifted by a good friend. It's an Ohira Tomae from the Imanishi stone company in Kyoto, was mined in the early 70s, graded by Mr. Imanishi, and was stored in his basement.With Jnats i have and all of you have
Please post pics of your J-nat ! All stones is welcome from all vendors. Also some other Natural stones too !
My friend it appears you may be living the dream.Holy s#&t that escalated quickly! Went full retard, it all started with a knife and a king stone a few months ago... Now I fear my desk may fall over under the weight of jnats and the constant rocking back and forth from testing them out. View attachment 189766

You mean the "nightmare" haha nah it's good, I am definitely lucky!My friend it appears you may be living the dream.
Yeah when they asked if I wanted to get my rocks off I had better ideas...Somewhere he unwisely turned his back on the much cheaper "hookers and blow” option.
Very nice. The three stones in the front what are they? The two light gray could look like aizusHoly s#&t that escalated quickly!
