Ohira uchigumori koppa #185
A very generous koppa of Ohira uchigumori in an even gray color. I would suggest that
this stone should not be used with valuable antique katana swords, but it can be used on
tool steel or razors as a unique grit source for sharpening and polishing those steels. I
used it as a final stone for a razor and although it felt a bit gritty under the blade is did
bring the razor up to shave ready with out little effort or time and in the video below you
can see the edge was in the HHT 5 range. I am selling this stone as a collectors piece,
and or as a finishing stone.
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.This stone will be shipped with a tested tomonagura slurry stone.
