This bronze dagger was unearthed from a stone coffin tomb in Songguk-ri, Chochon-myeon, Buyeo, Chungcheongnam-do. It is called a Liaoning-type bronze dagger or a Chinese lute-shaped bronze dagger. The part near the handle is wider than the rest, and there are protruded parts in the middle of the blade. The groove made on the shank is not a feature of the Liaoning-type bronze daggers made in Liaoning, China.
