AOTO Natural Sharpening Stone 9.5kg (20.9lb)
Size of Aoto: Approximately 260mmX240mmX90mm
I have got it from Kameoka, Kyoto whetstone company about 10 years ago.
At the time, Aoto is very hard to get it, and I had kept asking whetstone companies in Kyoto to sell me Aoto, but none of them had it, or all booked what they have.
However, it was not cut to sharpening stone sizes yet, so I tried to cut it myself after imported, but I have not cut it yet and keeps it in my inventory room.
If you have stone cutting saw or Countertop installer friend or display.
Aoto ore is not easy to get it, so it might be great display.
