This is a Shōhonyama Okudo Renge Suita finishing stone from Kyoto, intended for the final sharpening and polishing of knives and traditional woodworking tools.
Often referred to as the "Holy Grail" of Japanese natural sharpening stones, Okudo Suita has become extremely rare and highly valuable because the mine has long been closed and the remaining stock has largely been exhausted. Okudo is widely regarded as the King of Suita stones.
Okudo is one of the legendary Five Higashi-mono (Eastern Mines), alongside Nakayama, Shoubudani, Narutaki Mukai-da, and Ozuku. Among Suita stones, few can match Okudo for its combination of fineness, sharpening speed, and ease of use. It is also generally considered superior to the excellent Suita stones from the Shinden mine.
The kanji 奥殿 is sometimes pronounced Okuden or Okudono, but among natural stone enthusiasts the accepted reading is Okudo.
A partial Renge pattern is visible on the surface. The stone has medium hardness with high abrasive performance. The brown lines are non-toxic natural lines and cannot be felt during sharpening.
Reverse Stamp
梅ケ畑砥石 中勝 山本男系山主精選
Translation:
梅ケ畑砥石 (Umegahata Toishi) – Sharpening stone from the Umegahata district.
中勝 (Nakakatsu) – Nakakatsu, the seller or distributor.
山本男系山主精選 (Yamamoto Dankei Yamanu-shu Seisen) – Carefully selected by the Yamamoto family, the male lineage of the historic mine owners.
The 山本男系山主精選 stamp is especially desirable, as it confirms that the stone was personally selected by the Yamamoto family, whose lineage is historically associated with the Umegahata mines.
The 奥殿 stamp identifies the stone as originating from the Okudo Mine.
