In the tombs of the period when Korean-type bronze daggers existed, various composite objects associated with bronze daggers, such as hilts, dagger pommel fittings, scabbards, etc., were also buried as grave goods, forming various compositions. The period in which Korean-type bronze daggers existed could be divided into 7 temporal stages as a whole. In Stages Ⅰ and Ⅱ, only bronze daggers were buried and all composite objects were excluded. In Stage Ⅲ, a complicated pattern with multiple composite relationships appeared for the first time, albeit on a limited scale. Such a trend led to the formalization and burial of bronze daggers with multiple composite relationships in Stage Ⅴ, and to the formalization of such burial aspects in Stages Ⅵ and Ⅶ. At that time, the change of composite patterns was deeply related to notions of burial and burial conventions associated with bronze daggers, as well as to the renegotiation of the significance of burying the bronze daggers by the groups that owned them. The burial methods of bronze daggers and composite objects also continued to be gradually transformed. Although they were not generally revealed as features in Stage Ⅰ, they were deposited and then buried either in the coffin by early groups in the Korean-type bronze dagger culture or in the grave boundary by dolmen groups. However, in Stage Ⅱ, of the two above-mentioned methods, only the former existed. In Stages Ⅲ to Ⅳ, away from the existing burial method in the main distribution area of the Korean-type bronze dagger culture, there were some methods, such as deposition in a coffin for bronze objects (such as bronze daggers, etc.) or smashing and then scattering those objects against a coffin lid, etc., which had resulted in regional transformations centering on the Jeolla provinces. In Stages Ⅴ to Ⅶ, the method of burial by laying bronze daggers with multiple composite relationships in a coffin was formalized in the same context as the change of composite patterns.
