Sageo used to tie the sword on your waist as a belt in the old time, but now we usually tie on the saya. A sageo is a hanging cord made of silk, cotton or leather that is passed through the hole in the kurigata of a Japanese sword's saya. There are a number of different methods for wrapping and tying the sageo on the saya for display purposes. In some schools of Iaido, the sageo is tied to the hakama when practicing.
