From the Musashi Gold Collection comes this intricately hand crafted Umi Katana. Hand forged using 1045 & 1060 steel using the traditional Japanese method of Kobuse-kitae. This method uses a soft steel core in a hard steel jacket to improve overall shock absorption while cutting through hard materials. The blade hardness is 58HRC. The handle is ray skin wrapped in traditional white cotton cord. It also features an oxidized brass tsuba and fittings. Included with this katana is a maintenance kit to make sure your katana lasts a lifetime as well as a beautifully crafted sword box.
