A "cumai" katana is crafted using twisted damascus with 1095 and 15n20 steels, starting with a billet forged in kerosene before being shaped, twisted, and flattened to create a specific pattern. The process also involves blackening steel fittings with hot salts, engraving a maker's mark, wrapping the handle, and constructing a scabbard through milling, gluing, shaping, sanding, and painting for the final product.
