Our toughest swords in the Musashi collection come from the Miyamoto Collection. These swords consist of either T10 steel or Tamahagane. T10 steel is a tungsten alloy steel that has an extremely high carbon content combined with a bit of silicon. This makes for an exceptionally hard blade that is impervious to scratches and abrasions. Tamahagane, literally translated means “jewel steel,” is one of the rarest materials used in katana forging. The forging process to create a sword using Tamahagane takes several months to years. Due to its difficulty each Tamahagane sword is as unique as the sword smith that created it and truly one of the must-have swords in any collection.
