This Japanese sword Wakizashi has been hand forged using the ancient method of sword making. Full hand forged, hand polished. This sword is made of folded steel with 13 times folding to create the 8192 layers, which cast flexibility and hardness of the blade in a large degree. The visible tenuous undulating grain on the blade was resulted from folded repeatedly during forging. The clay temper process combines the characters of toughness and flexibility and results in a genuine hamon(temper line)..
