Ohira renge suita #717
Ohira is famous for their suita and uchigumori stones, the mine is
still operated by Ishihara-san who's 150 year old house is about
2 miles from the path leading up to the mine. He has one part time
employee but neither of them have actually extracted
any stone from the mine for almost 10 years.
This is a thin but very pure piece that contains both black and red
renge particles. I consider this stone to be a pre-finishing stone,
it is very fine but not quite fine enough and the relative softness
inhibits the creation of ultra fine edges on its own. An excellent
stone to couple up with a hardtomae though and it is quite wide
and convenient as a hand held stone.
The stone (toishi) has been lapped perfectly flat and the corners
beveled unless otherwise noted. All of my stones come with a
money back guarantee minus the return shipping.
