Aiiwatani is not something i get often. Located north for Kyoto along with Takashima
Now i know why so many confused Aiiwatani with Nakayama stones, they act pretty much the same and feel super smooth
Produce some of Harder and finer stones that is very fast.
This one can also be used on razors.
Super Yellow Aiiwatani Almost perfect no lines or impurities at all
Super fine too. semi mirror finish
I will say it act same as Nakayama kiita
Very hard to find stone perfect like that :)
