This Naurtaki aka-pin has areas of egg plant purple along with streaks of green and hints of yellow that can be
seen in sunlight when the stone is wet. From one of the shallower layers in the mine this stone is
only medium hard and is easy to use.

I honed up a razor using a light slurry made with a diamond plate following
The Ax Method and in
just a few minutes developed a HHT-3 edge with a minimum of effort. The resulting shave was
very comfortable, close and with no irritation of any kind. I am not a firm believer that only ultra
hard stones in the 5++ range are suitable for razors. Try this stone and I will guarantee your
results and satisfaction.

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 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.
