NANIWA YAMATO Compact Super Ceramics Whetstone – Portable Japanese Sharpening Stone for Knives & Outdoor Use (135×45×15 mm)
The NANIWA YAMATO Compact Super Ceramics Whetstone is a portable sharpening stone developed from NANIWA’s flagship Super Ceramics series.
Designed for small blades and knives, the YAMATO model delivers the same high grinding performance as full-size stones in a compact and lightweight form. It is especially suitable for pocket knives, folding knives, outdoor knives, and small precision blades where larger stones are less efficient.
Because of its compact size, the entire sharpening surface can be used effectively, reducing uneven wear and making maintenance easier compared to standard-sized stones.
The stone uses WA abrasive material and a magnesia bonding structure, providing strong cutting power and stable sharpening performance. It requires only water on the surface before use, making it convenient for both home and field sharpening.
A dedicated stone base is also available, allowing stable use in various environments, including outdoor settings and workshop use.
Ideal for outdoor enthusiasts, craftsmen, and users who need a portable yet high-performance sharpening solution.
