Kashin Katana
This katana is crafted using T10 steel plus ancient alchemical steel. It is made using the traditional "甲伏せ鍛" (Kabuse-tan) technique, also known as Jacketed Forging or Shell Forging. This Japanese sword-making method provides a structure that not only offers excellent edge retention and sharpness but also maintains the blade's toughness and resistance to breaking. The heat treatment involves clay tempering, further enhancing the hardness of the cutting edge.
