Hayabusa HAP40 Honesuki 150mm
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 a bit more slowly than some purer carbon steels.
This series is ground very thin and should be excellent for more precision tasks. This series comes fitted with octagonal wenge handles with buffalo horn ferrules.
Edge length: 149mm
Height at heel: 38mm
Spine thickness above heel: 1.9mm
