#2122 Hoard Ohira Suita with renge

A super saturated red renge suita from the Ohira mine. A Hoard stone, this is  medium hard that is easy to use with hard steel tools or razors. The base component of this includes yellow sands, and red renge.

I honed a Henckles razor after bevel setting on a 1k King stone. On this without slurry, just clear water after setting the bevels edges began to  refine and I could observe this happening within just 20 strokes. I deem this to be a very fast cutting stone. Next I made a light slurry with a tomonagura and this speed up the cutting by many times over.

This stone can easily hone up a straight razor, or be used to sharpen a tool or a knife blade to razor sharp. A rare stone considering that the Ohira mine was opened in the first half of the 1800's. This stone was mostly likely mined in the last half of the 19th century.
There is one corner missing on this stone and the price of the stone is reflected in the value. I also found one very minor bias seam towards one end outlined in the bottom photo. Needless to say this is a fairly important stone.

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