What steel grade is used in Tensa Zangetsu replicas?
Updated Feb 2026
Our Tensa Zangetsu replicas are available in 1045, 1060, and 1065 carbon steel. The number indicates the carbon content - 1045 contains 0.45% carbon, while 1065 contains 0.65%. Higher carbon content generally results in a harder, denser blade with better edge retention, which is why 1060 and 1065 variants are favored by serious display collectors. The 1065 steel versions may also undergo clay tempering, a traditional Japanese process that produces a visible hamon (temper line) along the blade's surface - a detail that adds both visual authenticity and collectible value. For display purposes, all three grades deliver impressive weight, finish quality, and long-term durability when properly maintained.
