150mm Hatsukokoro Hayabusa AS Petty Utility Wa HandleH & K is a Japanese knife manufacturer and their house brand is called Hatsukokoro. The brand is supplied by a handful of manufacturers from different notable knifemaking regions such as Seki and Tosa. Our first import shipment from H & K included the Kumokage line and the Shinkiro line. The Hayabusa lines also come in other high grade stainless and semi stainless steel. We think they offer exceptional performance and beauty for the price. Location:
