Vintage Ozaki iro (color) kamisori toishi.
A vibrant natural stone with remarkable sharpening qualities from the closed Ozaki
mine, these bright color Kyoto stones will never be mined again. Super fast cutting
and ultra smooth grit, a true finishing stone that provides with ease an edge that is
comfortable and close on any blade.
In general the stones mined in the last 40 years are super hard and harsh and cut
very slow, these first half twentieth century stones from the famous mines were
slightly softer and responsive to a greater variety of steels.
I just shaved off this stone and came away with comfortable shave that was
smooth 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. Coming from a 6k
Suehiro I spent 3 minutes on this stone and immediately after 20 strop strokes on
the palm of my hand I got HHT-3 tests all along the blades edge.
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.
