Here are some of my Rare stones:
Ozuku Karasu as in picture above
Super hard stone the hardest i have ! I only use it for western razors razors, it is so hard , i ones tryde to make microbevel on Yanagi with it and it chipped the edge very badly, like 2-3 mm chips
Nartuaki Karasu Momiji Suita
Hehe very long name but true, that stone have almost all appearances in it, in the middle layer of the stone there are 20mm very dark layer of Karasu so with time it will be very hard stone, but now it is very good stone for knives. Also line is not toxic or can not be field.
Of coars my Aizu:
These stones are instinct, can not find them anymore Very hard Aoto like stones, super fast also on some very hard steels.
Ozuku set, Very old Ozukus one medium one is hard, they come from behind Ozuku from Another opening then reguler used in Ozuku stones
Old Takashima Kiita, you cant get them anymore in that sizes or that uniform it is 300 mm x 90mm stone
It is quite hard for Takashima and have very nice black Nashiji, no lines or any inclusions at all and layer very very uniform
My Hakka that i recived like that
Then i glued it up and still use it, works very good !!
Got is as gift in Japan, very hard and fine stone
Tenjyou Ozuku Sunashi
Very shallow layer stone but still super hard and fine, very unique and rare. I had to press 2 month to they will sell it to me haha ..

Thanks for sharing Maxim, very interesting.
Aizu actually interested me, especially after reading the story of it's prudction but, like you siad, it's extinct and likely can't be found.
The color on that Okuky Karasu is just awesome
Pure white Asano Tenjyou Nagura very nice stone for prepolishing for knives or for razors.
Nakayama Maruka very smooth stone final finisher for my Yanagis
Maxim could you possibly provide a link that describes what all the word mean and the grades and such?
I know I've seen something on your website before just can't seem to locate it!
I have come back to look at these a few times. Thank you for posting this. Very nice!
