This Hideriyama i picked up my self in Japan
Normally Hideriyama is a mine that produce more softer stones then other mines.
But not this as they come from very very Old stock ! This medium hard Hideriyamas is impossible to find and quite many will not even sell them in Japan !
This one is Huge raw stone that i was lucky to grab when we visited one of our wholesalers. He had only 2 that was in that hardness !
It is still very easy to use but its extra fast and extra fine.
Finisher for tools and Knives !! Finishes and acts similar to super expensive Ohira Suitas !
Very very beautiful lime yellow color with different patterns !
Very big stone !!
Collector Grade !
Max size: 260mm 120mm 30mm
