Old mine Okudo asagi. This stone is an ultimate razor hone, super fine and very fast and hard as nails.
Rubbing this stone with your finger it is difficult to believe that it will sharpen steel, but it will and with ease it
will take a blade through all the phases of honing, finishing and polishing if that is what you want.
Being a light gray color it will show black iron in clear water or darken a slurry quickly. I always hone with a
slurry made with a diamond plate and this stone used this with this method is way fast.
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.
