Featuring hand-hammered blades inspired by traditional Japanese forging, the Tamahagane San Tsubame Micarta series is the ultimate combination of performance and elegance. At the core of every Tamahagane Hammered knife is VG5 Japanese steel that is hardened to 61 degrees Rockwell, and bonded with two outer layers of softer SUS410 stainless steel. This construction creates a blade that is the perfect balance of sharpness and edge retention. The handles are crafted of fine Micarta that provides an impressive look and feel of wood while being more durable. Micarta is a pressed linen material that is infused with resin, creating a comfortable grip with no maintenance required. Razor sharp edges are skillfully honed to 14° and are highly polished.
