Vintage Ozaki iro (color) kamisori toishi.
A very fine and very fast cutting stone but not overly hard, in the 4+ range. I just
shaved off this stone and got a perfectly smooth and comfortable shave with no
harshness of any kind. This stone is in the 20+k range and with some technique
the slurry could be reduced to an even finer grit. Going from a 6k Suehiro I spent 2
1/2 minutes on this stone and immediately got HHT-3 tests all along the blades
edge and with some skill even better results could be gotten.
perfectly flat with beveled edges.
This is a layer of stone that is totally depleted in the Kyoto mines. This particular
piece was mined in the 1950s or earlier.
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 the entire collection over a 2 year period. Many of the hones were actually
used by barbers, some dating to the 1920s 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.
