Sword Grade Binsui Tomo Nagura stones are practical, affordable sharpening tools ideal for medium-grit tasks. They can generate a consistent slurry on base stones, aiding controlled abrasion, or be used directly as a honing surface, acting as a substitute for coarse bevel setters without leaving deep scratches. Their gentle abrasion makes them versatile for sharpening knives, chisels, razors, and polishing swords, while preserving blade finishes.
