Saya are deeply lacquered in red, with a black ring-carved section at the sageo. The ray skin used on the tsuka is of the highest quality, and the tsuka-ito on the Katana and Wakizashi and the sageo on all three pieces are woven from best quality Japanese silk. The Fuchi, Kashira, Kojiri, Koiguchi and Kurigata are all made from blackened bronze, with decoration in relief and selective detailing of copper, silver and gold. The Tsuba of the Katana and Wakizashi, depicting the Kami, or Guardian Warriors, are made from hardened blackened copper, with decoration in relief and selective silver and gold detailing. The Habaki is of two-piece construction, the inner section being copper and the outer section gold-plated brass. The blades are engraved, at the Habaki, with a hand-engraved “Fudo” horomono, a traditional blade carving from the Edo period. The blades of all three pieces are grooved on both sides, and each piece features a long Kissaki.
