• Nihonkou

  • The Nihonkou collection features knives made from pure carbon steel, known as Japanese steel, which is less pure than white steel but offers a good balance of sharpness, durability, and cost-effectiveness. These knives are particularly suitable for processing plants and home use due to their resistance to chipping and ease of sharpening.
