The Hatsukokuro Hayabusa series is made from HAP40 high carbon steel laminated in soft stainless steel for easy maintenance. HAP40 steel has a hardness of ~66 HRC and is known for its incredible edge retention and great toughness despite being very hard. HAP40 will form a patina over time but more slowly than some purer carbon steels. This series is ground very thin and should be excellent for more precision-based tasks. This series comes fitted with octagonal wenge handles with buffalo horn ferrules. Edge length: 213mmHeight at heel: 45.6mmSpine thickness above heel: 2.1mmWeight: 140g **Please note that the knife pictured is not always the one you will receive. Due to the handmade nature of these knives, these dimensions may vary slightly. The color and pattern of the knife, handle and ferrule may vary from knife to knife.
