A traditional Kurouchi (black-forged knife) that carries the spirit of Japan’s nokaji — the independent blacksmiths who shaped blades for daily life.
Its rugged, unpolished appearance reflects a sense of warmth and authenticity that only handcrafting can achieve. The more you use it, the deeper its character and beauty become.
Blue Paper Steel No. 2
Forged from Blue Paper Steel No. 2 (Aogami #2), this knife combines carbon steel’s sharpness with improved toughness. The addition of small amounts of tungsten, chromium, and alloy carbides enhances hardness and resilience, making the edge more resistant to chipping and wear. Compared to White Paper Steel, Blue #2 offers longer edge retention while maintaining the same razor-sharp performance.
Because it is carbon steel, it can develop rust if left wet or exposed to salt — but with proper care, it rewards the user with a superior, lively sharpness cherished by professional chefs seeking a blade of higher quality and soul.
