#121 Nakayama  kiita koppa
Air Raid Shelter Hoard stone

One more kiita koppa of the purest color. This hand held size
kiita is very fast and easy to use, with just clear water or with
a slurry made with the accompanying tomonaguara or with a
slurry made with a diamond plate. The back and sides are
sealed in 3 coats of varnish. I have honed two razors on this
stone, a Henckels carbon steel and a  Japanese Kikuhide
carbon steel, both came out extremely keen and gave barber
type shaves.

This type of stone with the kawa on the sides
suggests that it was harvested from a nook in the shelf of the
stones layering. The mass of the stone is solid but you can
see thin inclusions that are solid and it is more than likely
they will never fail.

A tested tomonagura will be shipped with the kiita.

All of the stones in the Air Raid Shelter were from the same era
but I suggest several different mines. Each stone is totally unique
to the other and are not like any processed stones that I have
found in the past 39 years that I have been buying natural
stones from Kyoto. These stones were cut and finished, judging
from the hand cut saw sides, before 1920 and most likely in the
Meiji Era from 1850s to the early 20th century. The colors, shapes
and granular patterns of the hoard are much more organic then the
20th century stones that most of use are familiar with. I have found
and you will feel by testing this stone that the sharpening qualities
are not like the plain monolithic generally colorless stones that are
on the market in this first quarter of the 21st century. These stone
have all been superior in both cutting speed and fineness to the
modern processes stones and the hardness factor is a notch below
the current flood of stones too. These stones are very much
User Friendly as my clients are reporting back to me.

I would recommend that any and all of the Air Raid Shelter stones
be sealed on the sides and the ends and the backs could be an option
if any vulnerable cracks or inclusions appear. I will be willing to do this
for you is you wish.

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.
