HAP-40 Steel

HAP-40 is a high-performance, powder steel known for its exceptional edge retention, extreme hardness (up to 68 HRC), and fine-grain structure. Japanese knives made from HAP-40 steel offer outstanding cutting performance and stay sharp longer than most traditional carbon or stainless steels. Ideal for professionals and serious home cooks seeking durability, precision, and minimal sharpening. Despite its high hardness, HAP-40 maintains toughness and is less prone to chipping than many super steels.
