#400 Nakayama karasu tennen toishi

A very good example of karasu from the Nakayama mine. Mounted on
a carved fitted old wooden dai that reads on the bottom "hope" in katakana.
This vintage graphic barbers stone contains several elements often seen in
stones from Nakayama including strongly defined and dark black crows against
a gray sky, straight namazu lines as seen on one side, ultra fine grit and
patches of kawa seen with ocher and or umber or burnt umber colors and
often but not always as it is sometimes removed, areas of black with
crystallized grains that can be seen as individual distinct twinkling particles
when viewed with the naked eye in direct sunlight.

The black crystals on this stone are flatter than what I prefer to see, and the
umber and burnt umber are missing but also is missing 95+ percent of
the original kawa that this stone originally had intact which was at least
on both sides as evidenced by the remainder, and most likely on the back of
the stone judging from the tan coloration. Luckily I am the owner if a
authentic Nakayama karasu to use as a sample for comparisons.

The stone (toishi) has been lapped perfectly flat and the corners and
edges beveled unless otherwise noted.  All of my stones come with a tested
and appropriately sized tomonaguara slurry stone, and a money back
guarantee minus the return shipping.
