Nihonto is a long piece of iron. The sharp blade and "Nakago" or hilt, which is inserted into "Tsuka", a decorative grip. The hilt is anchored to the grip, using "Mekugi", a small piece of bamboo that's inserted into a cavity of the grip and punched into the "Nakago" so it won't slip out. "Tsuba" or handguard is placed at the end of grip. Each mounting, called "Koshirae", is one of a kind and has its artistic characteristics. The scabbard for Nihonto is "Saya". There are decorative ones and plain wooden ones used for blade storage.
