Here’s a uncommon Tomo or Koppa - depending on how you look at it. This is quite large, but I’ve been using it as a finishing Tomo and for dressing the working surface of several Tennen Toishi.
I give the nod to Kiita here, but there is some doubt… it could be Asagi, but my guts say Kiita. Whatever the story is, the banded coloring is nice to look at, and it makes a great finishing slurry on very hard stones.
