Yesterday I got a new Oozuko stone to play with.
I wanted to try something very hard, and boy did this stone deliver.
After 30 mn lapping session with DMT XXC (120) it is still not completely flat, there are spots close to the corners that are a bit low. I managed to lap enough useful area to test though. The edge was very smooth and really sharp, no harshness what so ever. The real color is very light gray very uniform except for the two brownish spots. The slurry is milky white and the stone feel buttery during honing.
The next one is a rare bird.
According to the information available from Morihei and JNS
It is not a Kyoto stone but North Japan stone. It was mined in the summer and cut in the winter indoors, but because the weather was cold outside all windows were closed so all worker got lung disease and died around 1950, so no more made after 1950th.
The stone is very similar to Aoto in grit (~3-5k) but harder, this one has very nice blue figuring. Cuts fast, probably a bit faster than Aoto, and the slurry breaks down rather quickly. Very cool stone IMHO.
