Polished Stone Dagger, Gimhae-si, Korea, Early Iron Age. Stone - Clay Slate, L. 66.7cm. Acc. No Sinsu2662 © National Museum of Korea

This polished stone dagger was excavated from a dolmen in Mugye-ri, Jangyu-myeon, Gimhae, Gyeongsangnam-do. The blade and hilt of this 52cm-long dagger were produced as one unit. The cross-guard is extended more than necessary, leading experts to presume that it was intended for a ritual purpose rather than for use as a weapon.
