The texture is characteristic of sedimentary siltstone\/sandstone typical of mid-grit Japanese naturals.\u003cbr\u003e\u003cstrong\u003eAccompanying Piece:\u003c\/strong\u003e It includes a matching (Tomo nagura\/Slurry stone) cut from the same stone material, useful for cleaning the surface, pre-conditioning the bevel, or raising an initial slurry.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eDimensions \u0026amp; Weight: \u003c\/strong\u003e210 mm × 80 mm × 45 mm, weighing 1,803 g.

It offers comfortable tactile feedback with decent slurry generation under moderate tool pressure, without dishing excessively fast.\u003cbr\u003e\u003cstrong\u003eCutting \u0026amp; Finish Profile:\u003c\/strong\u003e Excellent toothy, semi-matte\/hazy finish on cladding and core steel. It serves as an ideal intermediate step between aggressive shaping stones and fine pre-finishers (such as Aizu or fine Suita), leaving a functional working edge with aggressive bite for utility and kitchen blades.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eMarkings \u0026amp; Stamps\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eGrade Stamp: \u003c\/strong\u003eA distinct oval seal stamped on the side reading 特選 (Tokusen), translating to \"Specially Selected\" or \"Choice Quality.\"\u003cbr\u003e\u003cstrong\u003eOrigin Stamp:\u003c\/strong\u003e A rectangular boxed stamp located near the opposite upper corner on the same flank, partially weathered\/faded, denoting the regional distributor mark.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFlaws, Inclusions \u0026amp; Structural Condition\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003ePerimeter Chips: \u003c\/strong\u003eSmall breakout chips and irregular edging along the bottom corners and bottom edge bevels (visible on the underside), typical of sawn quarry blocks that have not received an aggressive secondary chamfer.\u003cbr\u003e\u003cstrong\u003eSaw Marks: \u003c\/strong\u003ePronounced diagonal gang-saw \/ wire-saw striations across the sides and underside.
