This light gray stone from the Umegahata valley in Kyoto is probably from either the Shobu or Okudo mine
judging from the skin and the stones consistency. This stone was tested with a straight razor and it is definitely
a razor hone quality, but it is also very large so it could be used as a final stone for tools like plane blade or
paring chisels. When you first pick up a stone like this it is so smooth to the touch that it is hard to believe it
could actually sharpen steel, but I assure you that it is full of grit and is a very fast cutting stone.
Using TheAxMethod I was able to quickly go from a bevel set with a 2k Shapton to a final finishing step in just a
few minutes and the resulting shave was not only close but very comfortable. The price of this stone reflects
the cut and clipped corners as it came from the stone wholesaler.
A tested and matched tomonagura will be included with this stone. All of my stones come fully lapped with
beveled edges unless otherwise noted.
This stone and the other kamisori toishi on my site are from a world class private collection of over 400 pieces
assembled in Japan over the past years in the area around Toyama by a collector of shaving implements. I
was lucky enough to purchase total collection over the last 2 years. Many of the hones were actually used by
barbers, some dating to the 1920 s or earlier, while others were simply prepared by the miners as razor hones
as evidenced by the size and fine quality of the stones grit composition.
