I can;t remember the translation, but the stamp does not say anything about the stone.
This is a 330mate stone so it can be anything

As above. They are 330mate.com's stamps. Not really an accurate identification of the stone.

Thanks Onimaru55 and Mainaman...

I guess it really doesn't matter knowing what it is as long as it works...appreciate the response!

Looks like a stone from the namito layer. Should be a hard and fine stone.

I wouldn't know about the 'layer'...hell I don't even know what a 'layer' is! ... but it is very, very hard! I have a very nice and very hard Llyn Idwall stone and this JNAT is as hard as that...maybe even harder. I use a Carborundum #102 Razor hone to raise a slurry on it, and I really have to work at it to get a decent slurry. But like I said it puts a super smooth edge on a blade!

Thanks for your response SharpMan!

Sharpman, I am sort of hanging out with you in the Namito or Aisa strata on this one. These deep stratas are always hard stones and sometimes scratchy hard. Wolfpack says it hard and it also looks like it has a faint Karasu pattern, a type of stone found in that depth in the Asia strata right next to the Namito. Nakayama karasu more often than not have a more sharply defined black patch on the gray background, this is fuzzy suggesting a nearby mine like Narutaki. Without looking at the skin of this stone the Nakayama attribution is more difficult to ascertain.

I am diggin the shape of the stone and lucky for you and your razors that you have one long straight run on that one side. Are you using the stone with a slurry for honing, if so you might try a really worn out diamond plate as a "diamond nagura" and leave the Carborundum out of the picture and off the table? Alx

I can't be certain of course, but I have seen so many(thousands) natural stones
and I always pay attention to their looks and what mine and strata they are from.

OP says the stone is very hard, so very likely from a deep strata. It does not
look like suita at all, so probably tomae, namito or aisa strata. Looking at the
colour of the stone I see this greenish colour, and tiny hints of karasu
which makes me think namito the most and maybe aisa. And I get a ''namito
feeling'' looking at the stone. Might be aisa or between both.

Brilliand minds think alike Thanks for the information about the difference between
nakayama and narutaki.

Alex I have the feeling that ( I ) one can see the difference between
nakayama karasu and karasu from other mines. Do you think this is possible?
Karasu from Takashima mine looks very different to nakayama karasu, at least
the ones I have seen.
