Nakayama koppa iro tomae #170

Beautiful iro tomae from the Nakaykama mine. I suspect that this stone was
mined in the mid 1960's by Kato-san. Because it has kawa skin on all four
sides and the back the indications are that it came from a nook in the mine,
a corner of the shelf or cavity. This is a razor grade hone, and although it is a
level 4+ in hardness it will create a shave ready edge if you approach it with
a light hand. The colors are yellows and hints of rouge, the kawa skin is
made up of ochers, umbers and burnt umbers and two patches of black with
a sparkling element.

As a hand held size and shape, it is thin so a wooden base would bring it
off your palm a bit more

The stone (toishi) has been lapped perfectly flat and the corners and edges
beveled unless otherwise noted.  All of my stones come with a money back
guarantee minus the return shipping.
