These are relics unearthed from a tomb dating back to the early Iron Age in Bisan-dong, Seo-gu, Daegu. The spearhead was used by inserting a wooden handle into its end and fixing it to the semi-circle ring at the end of the spearhead. Three items were unearthed, one of which is 67.1cm long. It is one of the longest socketed spearheads ever found on the Korean Peninsula. Another one (length: 57.2cm) has no hole in the ring attached to it, leading researchers to believe that it was used for ceremonial purposes. The third one (length: 40.0cm) is in good condition. Many of the socketed spearheads found on the Korean Peninsula are those made in imitation of those made in China, but these are completely localized ones.
