Hwandudaedo

ring-pommel sword) is the modern Korean term for one of earliest original types of Korean sword, appearing in the Proto–Three Kingdoms of Korea.

The hwandudaedo was a large military sword made for battle, as it had a thick back and sharpened blade.

This sword's name was given because of the round shape of the pommel (daedo 대도把頭).
