These are Korean-type bronze daggers excavated from the archaeological site in Namseong-ri, Sinchang-myeon, Asan, Chungcheongnam-do. (A total of nine daggers were discovered.) The body and handle of the Korean-type bronze dagger were separately made, as was the case with the Liaoning-type bronze dagger. Compared to the Liaoning-type, however, its body was straighter and the indentation in the middle was sharpened to form joints. Along with the findings at the archaeological sites in Goejeong-dong, Daejeon and Dongseo-ri, Yesan, the relics excavated from Namseong-ri, Asan show the earlier features of the Korean-type bronze dagger culture established in the southwestern part of the Korean Peninsula.
