Full Description
Full Description
This Aiwadani natural stone is valued for its even structure and stable sharpening behavior. Rather than pronounced lines or dramatic patterning, the surface and internal composition are uniform, supporting a consistent interaction between stone and steel.
Within the Aiwadani strata, stones of this type are known for their predictable response and steady feedback. The abrasive material is well distributed, allowing for controlled slurry development and an even working surface. This contributes to smooth, repeatable results, particularly during fine finishing stages where control is more important than speed.
Geologically, Aiwadani belongs to the same broader sedimentary system as the Kyoto whetstone mountains, despite its location in present-day Shiga Prefecture. As a result, stones from this area often share comparable mineral composition and working characteristics, while retaining subtle differences shaped by local pressure and deposition conditions.
In practical use, this stone integrates naturally into a traditional finishing progression. It supports gradual refinement and surface uniformity, responding clearly to changes in pressure and technique without sudden shifts in behavior. The sharpening feel remains calm and consistent throughout use.
This piece was selected for its structural consistency and dependable working qualities, making it a reliable finishing stone for users who value clarity, control, and repeatable results.

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.
