Hideriyama is a mine that produce more softer stones then other mines.
It is very good stones for Kitchen knifes or for beginners in tool sharpening!
This one is super smooth and feels a lot like Hakka maybe even bit finer !! , very good deal for such uniform and smooth stone !
Makes perfect Hazy contrast finish and super easy to use
Make perfect kasumi finish very easily !
Need some flattening
