#2104 Nakayama kiita tomae
Air Raid Shelter Hoard stone
Another early mined stone from Nakayama showing the kawa skin that is made
up of ocher, umber and burnt umber colors along with a black mineral element
that sparkles in the sun as crystals. I did lacquer the sides knowing that this
medium hard stone would benefit by being sealed, there was at one end an
inclusion that was not open but did absorb water differently. A really fast cutting
stone in a knife or tool size but I test these stone with a razor to indicate the
keenness quotient and this stone gave the Henckels razor a perfect edge.
The upper group photo collage shows the stone as it is now after I sealed
the sides and ends with lacquer while the lower group photos show that the
sides and ends as they still are under the lacquer. This stone was shaped
from the raw using hand saws, the back was hand chiseled with a geology
hammer of the kind thatwas common for stone workers to use up until
the 1950s. The top has been lapped and polished and the top edges beveled.
With a splash of clear water the stone when used with a knife or tool
will peal away black swarf easily leaving hard steel of any kind
with a shiny chrome shine. If a slurry base is created the cutting powers
are accelerated and the slurry turns jet black in just the first few strokes
as you can see in the video below. I have also honed several western
straight razors on this stone which produced very keen edges resulting
in barber close shaves.
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.
