Full Description
Full Description
This Nakayama natural finishing stone originates from Mt. Nakayama in Kyoto, one of the most respected sources of high-grade finishing stones. With an estimated grit of 8000 and above, it is suited for final polishing and edge refinement.
The stone is slightly hard, offering a very smooth, controlled sharpening feel. It is capable of producing a true mirror finish, particularly valued in traditional ji-duya work on Japanese swords, where surface clarity and evenness are essential.
Unlike larger bench stones, this piece is shaped to sit naturally in the hand. Its size and balance make it well suited for one-handed honing, while still providing excellent control and feedback. It can be used on knives, kamisori, and razors, especially where a fine polish and smooth edge are desired.

Care Guide
Care Guide
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.
