#393 mottled black karasu

Karasu were found in small quantities in most of the mines but in all honesty
I do not actually know which mine this one came from. The kawa skin on the
back suggests it is from the Shobudani mine but I do not have any other
examples of this kawa pattern to make a comparative decision leaning
one way or the other.

I have however tested this karasu for razors using a Henckels blade and
found it to be super fine and perfect and resulting in excellent shaves but it
is a slower cutting action so you have to work at refining the blade. I suggest
that this should be a final stone and be used as a polisher after going through
a progression from bevel setter that includes a good Honyama middle Jnat
natural / 3,000 synthetic equivalent followed by a Jnat / 6k to 8k synthetic.

Marked on the back in katakana is the word Tonbo which translates as
Dragonfly, but I feel that this is an allegorical description of some form and
has little to do with the stones origin. This is a large 209mm long full size stone.

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.
