An authentic, high-quality Japanese Natural Whetstone (JNAT) from the renowned Shohonyama quarries in Kyoto, Japan. This piece is a "White Suita" (白巣板) featuring a distinctive "Namazu" (ナマズ) pattern. Known for producing excellent slurry and a highly refined, razor-sharp finish, this stone is perfect for sharpening high-end kitchen knives, traditional Japanese razors, and woodworking tools like chisels and planes. It is a compact "Koppa" (irregularly shaped stone), offering professional performance in a practical size.
