#10 Mikawa Shiro Koma Nagura

This shiro white nagura makes an excellent middle stone, inserted
between a bevel set and the final finishing stones. It will remove metal
from the hardest razors leaving a more polished surface. I found that
these base stone nagura are easier to use if you soak them for 1 to 2
minutes so the hydration becomes consistent. Splashing clear water
as you go along will keep them cutting.

A totally unique koma nagura with a "popcorn" kawa. Although there are
none of the commonly seen kawa colored minerals, this is the back
of the stone, and it represents a very different complexion from the front.
The base silica mineral of this stone is extremely pure and snow white
and this stone could add an important grit source for razor sharpeners
or for blade polishers of knives or other fine metal products.

Becoming very scarce in this size, I do not know how long I can continue
to source them from my nagura miner who keeps telling me that these
will be the last he will every see. He is old so I believe him.
These and all of my other bench size Mikawa nagura do not have Asano ink
stamps or any other attributions because I circumvented the stones before
Sakamoto-san the owner of the Asano stamps had a chance to make his a bid.

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