This stupidly large kiita koppa from Shobudani is a nook stone, pulled out from the edge of the end of the sediment layer where the volcanic waste begins to fill in the irregular voids surrounding the awasedo. With kawa skin on all sides save the top where it was ground clear and flat, the back was flattened just enough to rest on a table.


I have honed antique steel razors and modern boutique blades on this stone. It rejects none.

A lifetime tomonagura will be included. All of my stones come with a money-back guarantee minus the shipping.

Excluding Sales Tax
  • All of my stones are sold with a money-back guarantee minus the return shipping if within 30 days of the sale and returned in their original state. Please do not lacquer the stone if you have any intention of returning it.

    I encourage sealing the sides of all sedimentary stones, especially if there a inclusions, cracks, or fissures and or if the stone is used in an active workshop where the stone is constantly wet. For casual use, sealing, especially all four sides, and preferably the back with one of either a marine type of spar varnish, a synthetic lacquer, urushi, or a cashew-derived lacquer is prudent.
