Gousa is a seam that is either in-between Aisa and Tomae, or actually in Tomae or Aisa but close to the separating line.
We have here a wonderful razor-quality stone that can also double as a high-end finisher for cutlery. Please note that it is rare to find a Toishi from Okudo that is so very hard; and this stone is quite hard indeed. It is dense, tightly packed full of extremely friable and uber-fine silica. Honing on this is a dream. It’s a true heirloom stone.
