Sageo Wrapping of Katana Sword
The Sageo (下げ緒) is a cord that extends from the kurikata knob on the saya (scabbard). When the sword is not in use, it is tied in special ways to look presentable. The sageo itself can be made from silk, cord, leather etc. It is generally good form for the sageo color to match the tsuka-ito color (handle wrapping).
