Vintage Ozaki classic asagi kamisori toishi.
A very fine and very fast cutting stone that is also very hard, in the 5+ 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 30+k range and with
some technique the slurry could be reduced to an even finer grit. After making up a light slurry with a diamond
plate I went from a 6k Suehiro and after that within 2 1/2 minutes on this stone and immediately got HHT-4 tests
all along the blades edge and with some skill even better results could be gotten.
It is lapped perfectly flat and has beveled edges as you can see in the photos, the side are lacquered. The back
shows the natural strata skin called Kawa.
This stone is from the Ozaki mine, a Hashi-mono mine now closed that was in the upper reaches of the
Yamashiro area mines. This particular piece was mined in the 1930s or earlier but most likely slabbed up in the
50s, the character of the asagi is the classic variegated blend of a sea green and a metallic indigo. This is a
subtle but unique coloration and very different from some of the more modern slower cutting slate gray asagi
stones. The deposits of stone like this are now depleted and the historic mines from which they came are closed
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.
