Une véritable pierre d’établi : 30 cm de long, 11 cm de large, un peu plus de deux kilos. Marquée 正本山・shōhonyama, le cachet des pierres naturelles authentiques de Kyoto, sous le cartouche des pierres naturelles de Kyoto.
La face est d’un gris-bleu pâle, couverte d’un bord à l’autre de karasu sombres — les marques de corbeau qui donnent son nom à ce motif — avec de fins suji blancs dans le sens de la longueur. Les flancs sont laissés tels qu’ils sont sortis du lit, stratifiés et teintés de fer.
4,5 sur 5 sur notre échelle de dureté, grain d’environ 8000. Dure et fine : elle coupe lentement, donne un retour clair sous la lame et finit lumineux.
À cette longueur, elle accepte la course complète d’un couteau de cuisine, et sa largeur laisse la place au travail du rasoir sans encombrer la face.
Vous recevrez exactement la pierre présentée.
Description complète
Description complète
This is a full bench stone of Kyoto natural stone, stamped 正本山・shōhonyama, the mark that certifies genuine Kyoto material, together with the Kyoto natural-stone cartouche. At 30 cm long, 11 cm wide and just over two kilograms it is a true working stone rather than a hand piece. The face is pale blue-grey and covered edge to edge in dark karasu — the crow markings — with fine white suji running lengthwise; the sides are left natural, layered and iron-stained from the bed. At 4,5 of 5 on our hardness scale and an estimated grit of 8000 it cuts slowly and precisely, gives clear feedback under the blade and finishes bright. Suited to kamisori, straight razors and carbon steel kitchen knives. You will receive the exact stone shown.

Sharpening Care Guide — Natural Japanese Whetstones
To preserve the character, performance, and longevity of your natural Japanese whetstone, please follow these care guidelines:
1. Keep the Stone Flat
Natural stones wear more slowly than synthetic stones, but regular flattening is still essential for controlled sharpening. Use a diamond lapping plate or a suitable flattening stone to maintain a flat, even surface. Avoid aggressive lapping unless necessary.
2. Use Water Only
Natural Japanese whetstones are designed to be used with water. Lightly wet the surface before use. Some stones benefit from a brief pre-wetting, while others should not be soaked for extended periods. Do not use oil or chemical additives.
3. Slurry Management
Depending on the stone, slurry may develop naturally during use. This is part of the sharpening process and should be managed gently. Avoid excessive pressure or artificial slurry generation unless intentionally desired.
4. Clean After Use
After sharpening, rinse the stone thoroughly with clean water to remove metal particles and residue. Use a soft brush if needed. Do not use soap, detergents, or abrasive cleaners.
5. Dry Slowly and Naturally
Allow the stone to air dry completely in a shaded, well-ventilated area. Avoid direct sunlight, heaters, or rapid temperature changes, as natural stones can crack if dried too quickly.
6. Store with Care
Store the stone in a dry, stable environment. Avoid damp locations and protect the stone from impacts or sudden temperature changes. If stored long-term, ensure the stone is fully dry before placing it in a box or wrapping.
7. Inspect Before Use
Before each use, rinse the surface and ensure it is free from dust, grit, or foreign particles. Any contamination may cause scratches on the blade and compromise sharpening results.
By following these guidelines, your natural whetstone will retain its unique sharpening characteristics and provide consistent, controlled results over time.
