I was already fan of the knives made by Watanabe, now I had to try his stones.
At first, here are some pictures of the same blade sharpened with five of his stones. The AI#1000, Ikarashi-do, Shiro Suita from Maruo Yama, Shiro Suita from Ohira and Ao Renge.
(In fact I hadn't any knife needing to be sharpened with a coarser stone than a Shiro Suita, so this one is an horrible Aura borrowed from a colleague)

Ikarashi-do, hardness 5/10:
Shiro Suita, Maruo-Yama, hardness 6/10 :
Shiro Suita, Ohira, hardness 7/10 :
Ao Renge, Ohira, hardness 8/10 :
