This archaic-looking Genno is forged by hand in one of the last big hammer forges in Japan. The soft body is selectively hardened, then given a hammered look. Heating the soft steel to varying temperatures (250-300 °C) results in a coloured, shimmering surface. Each head is engraved with the name of the master blacksmith. Flat and curved faces. The handle is pre-mounted and must be wedged into the head by the user according to Japanese tradition. Instructions included.
