Yeah wet vs dry without proper lightning can do that.
Also in the wet shot the stone is turned around, if you look closely you will see the clouding is identical.

This is one of my favorite stones, super fine grit Lv5+, quite hard but not over cooked Lv5.

Not to disrespect, but i think these thread is for stones that is not for sale.

Thank you for pointing that out, from now on I will only add photos of stones from my own collection. respects, Alx
Yes, lets se some of our privet rocks :)
Well this is probably my rarest stone. Any pre-20th century dug Shinden kiita is exceeding difficult to locate. Shinden of course was closed early on and this stone was fitted up or precessed in the Meiji era or the late Edo period. Kiita are not all created softer, and this one is not, it is a fairly hard stone in the Lv5- range. The color of the wet stone in the photo is actual as you can judge by my netural background which I like to use as per Ansel Adams. Nakayama was famous for their kiita but the other nearby mines also had their share of kiita stone. I feel very fortunate to have found a rock from the early era. Some will say that "heck all these stone are old", this is geologically correct. But just as with the Coticules mines, the quality of stone in and of the early diggings was unique, and I doubt that anyone will dispute this. The same with the Honyama area. Alx

Here is another stone from my bottom shelf (less far to fall in an earthquake) private collection. A pre-20th century Nakayama gousa from the deep tomae or asia layer. Hand sawn sides using a noko, one or two man saw, this stone is not square nor is it flat on the back. Medium hard & very fine leaving bright edges on hard steel, hazy surfaces of wrought iron. Alx

hey alx what does that symbol mean on the bottom of that first stone you shown. it looks like three lines and a plus symbol thanks
Nice looking stone Alex. I think that colour is actually not called kiita in Japan, but ikimurasaki.
It's close to kiita. I say this because I have seen that exact same colour on Maruoyama stones
and they were called ikimurasaki.
I have seen some stones in this topic that barely have any kiita in them, yet
were sold as kiita.

I would like to learn more about the iki marasakai, any links? Alx
Alex, I googled a bit and found that ''murasaki'' means purple in japanese. Not
sure what ''iki'' means, but since I read that ikimurasaki is the most desired colour
after kiita I am guessing that it's a combination of ''kiita''(yellow) with ''murasaki''(purple).
I found this for ikimurasaki:

That is from Maruoyama mountain I think.
Sharpman
Several weeks ago I spoke with Maruoyama hones, and the Name Ikimurasaki is just that. A name.
You are right that murasaki is purple, and the name they chose was to describe the colour of the rock more than anything else.
He also said that there were better hones for razors than the ikimurasaki. He said 大谷山 Otaniyama was better. (his opinion)
The ikimurasaki are expensive because they are less common.
Here is a pic from Totoriya (Maruoyama Hones) of a pre cut section of the ikimurasaki.

As fare as i know name Ikimurasaki is only used of Maruoyama.
Kiita can be orange or yellow, but its only appearance, name, nothing to do with performance, layer or what quarry stone come from.
It can effect price very bright Kiitas go for 100 000 yen and up. But you pay there most for the look and beauty of the stone then performance.
Varieties of Nakayama: many of which are considered 'Kiita' (These are all different 'types' of Nakayama hones.)

I also understand that "murasaki" means purple.
The work Iki is a very important word in Japan and it describes a life style. In the Edo period it was forbidden by law to openly display your families wealth in an ostentatious manner, and this was during a time when the merchant class was overshadowing the samuri class in their fortunes. Iki is a life style that shows plainness on the outside but vivid and gaudy material on the inside. This style can be seen in kimono and in the art and theater of the era but is best understood in the homes of the merchant class of the times. An iki style home may have the most simple and often very linear architecture facing the street, all plain and dull, but inside it is full of color and opulence. This way the merchants could enjoy their wealth in private but at the same time follow the law.
By the way, the Maruoyama is a western mine deep in the Tamba region just outside the town of Kameoka. The Ohira mine is also nearby. These Nishimono mines are not noted currently for their fine grit stones, but more for the speed like in the suita stones from the area but this is not to say that excellent and very fine stones have not come from these mines. As I have said before, each and every mine has at one time or another produced some surperb stones, it is just that over time the mines centered around Yamashiro have been very consistant in super quality and percentage of output in that ultra class of stones.
Maruoyama is one of the last old time owner operated mines that is active, 3 generation of the same family are involved, lovely and honest people who are very approachable and I see them at the kezuroukai. Alx
Here are some newer jnats. an Ozuku Kiita lv 4.5 hardness originally from Maksim with tomo nagura. and 2 koma naguras.
the othe picture is the skin at the back of the Ozuku. I don't know how to use the Ozuku yet.
mainaman was generous and gifted me a beautiful tomo nagura but I will add the picture of that later.

This is my New Ohira Range Suita.
Very creamy feeling Lv 3 or so very nice stone and just super super fast. I can use it both on razors (not as finisher) and my high and knives.

Here is another Shinden that was probably slabbed up in the 1910s-30s. Very pure and consistent and heavy and dense. HHT-4 all day long from this stone.
http://www.thejapanblade.com/images/shinden300.jpg
Nice rocks indeed!
Alex I am curious to know if you have a video somewhere of doing HHT! :)
wow, nice job Doc, some of those were really HHT5s.
edit: like the one at 0:18
That was the sharpest I have ever gotten a blade. I don't usually do the HHT in this manner (few inches away from the edge) but I was playing around with this one. This was a razor I honed for someone else, they told me it was the sharpest and smoothest shave they have ever had.
Guys let's stay on topic here?
The thread is about J-nats not HHT, a separate thread would be most suited for discussing it.

I just answering Daniels request.
Here are my humble J-nat's. I don't have many but they are all great when used in sequence. I'm content.
Left: Ozaki Suita 4+ from Alex
Middle: Ozuku Asagi 5 from Maxim
Right: Nakayama Asagi 5 from Alex

I have to say that the edges I can now get since receiving the Nakayama are far and away the best I have been able to achieve.
Those are very nice hones. You appear to have all that you need to suceed and indeed your are getting great edges. Enjoy!

Got an Otaniyama the other day.
I've got Nakayamas, Ozukus, Coticules, Thuringens and some more, this one beats them all!
Does anyone now anything more about it?
I don't know anything about them, but I do see one thing I really like that a lot don't have. Thats enough stamps that you can seal some of them and not have to worry about lapping them off and losing the proof of what the stone really is. Enjoy it and let us know how it works.
Regards,
Howard

Nakayama something something...
Perhaps someone can read this kanji, it's a very nice stone, smooth as butter and a good prepolisher!
I've only got one test so far, by if the first is any sort of indicator to how it gets once I learn to know it I'm gonna love this stone :)
Okudo Karasu

Some more smaller razor stones...
Attachment 100578Attachment 100579Attachment 100580
Corner cut to make tomonaguras, there is usually some corner that is bad anyway.
I determined I would get a super-hard Karasu from somewhere.
I picked this up from a certain notorious Japanese ebay seller and even though I had a number of reasons to dislike it (huge toxic line, big chip came off during transit and it had been painted a lighter grey to make it look more even), it's become one of my favoured stones because I find it to be a fast, fine and very smooth stone to use.
I use it in the Asano Nagura progression stage and with a softish Tomonagura. Only takes a few strokes for the slurry to start turning grey - no need for circles or whatnot.
I wouldn't call it the hardest stone, just a step below that.

I managed to grab this stone from Maksim and it is my smoothest and I think hardest J-Nat. Super smooth Ozuku which, if used with pressure, is also very fast as I was naughty and sharpened some knives on it. I use it as my final finisher, just water to ensure the edge is perfect.
