#74 Nakayama kiita very large koppa
Unique stone with living edges all the way around of rich kawa. A dull kiita color, this is a hard deeper strata stone. Super smooth and fine I was able to hone a classic Henckels Friodur in just a few minutes after the 2k Shapton bevel set. Shave was a better barber type shave. Very solid it will last centuries. A very oversize koppa but likely the miner did not have the heart to cut it smaller.
This stone did come from the Air Raid Shelter Hoard. Rare example
in every way.
The stone (toishi) has been lapped 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.
