Traditional Saya Katana Scabbard. Saya is a simple name that refers to a Japanese sword scabbard. The scabbard is often constructed of a lightweight material such as wood and is lacquered on the outside. The inside of the scabbard can be lined with cotton or hemp cloth. There are several types of Saya used by Japanese swordsmen. They vary in size, shape, and material quality. All Saya feature a slit on one side through which the blade protrudes when drawn. The user draws the sword from this sheath by grasping the hilt with both hands and pulling it toward him or her. Katanas were usually kept at home for security reasons so they were rarely seen in public. However, during peacetime, they would be worn by farmers, merchants, and others who did not need their sword constantly at their side. Because of this reason, many swords have been found buried in farmland all over Japan. When wars broke out, everyone needed a way to carry their weapons so Saya were developed as defense mechanisms for horses. Since humans could use them too, they became popular items to customize for each rider. Even after horses were no longer used as transportation, they continued to be appreciated as decorative items placed in shrines and temples.
