This is a high-quality finishing stone from the renowned Shohonyama area, classified as Uchigumori (内曇). It offers an effective grit level around **9000**, delivering an extremely smooth, refined edge with excellent kasumi (cloudy haze) finish — ideal for razors, high-end kitchen knives, straight razors, and even swords.
Hardness: Lv 4.0 (medium-hard range for Uchigumori, providing good durability while still releasing slurry readily).
Dimensions: 167 × 83 × 27 mm
The surface shows visible **suji** (natural line patterns), which are typical and purely aesthetic — they do not affect sharpening performance or cause any catching/scratching during use. The stone is free of significant depressions or pitting, and has no cracks or bruising issues, ensuring consistent, reliable contact across the entire working face.
