Weapon refers to swords, iron spears, iron axes and arrowheads used for fighting. A good number of big swords, iron spears, iron axes and arrowheads were found in the Daegaya mounded tombs.

Of these, the big sword with a round pommel is a weapon that shows the character of the tumulus¡¯s actor most clearly. The pommels are classified into several kinds: plain ring pommels, tri-ring pommels, ring pommels with tri-leaf ornaments and ring pommels with dragon or Chinese phoenix ornament.

There are many ring pommels with tri-leaf ornaments in Goguryeo and Gaya, tri-ring pommels in Silla and ring pommels with dragon or Chinese phoenix ornaments in Baekje.

The big sword with a round pommel is very helpful in understanding the character of the tomb¡¯s actor. This is because the quality of the material, character and size of its ornaments are varying in accordance with the difference in power.

Among the big swords that the ruling class of Daegaya wore, the big sword with a round pommel on which dragon and Chinese phoenix ornaments are inscribed is the most typical one. This kind of sword was exhumed in the Jisan-dong Tumulus No. 33 and the Okjeon Tumulus No. M3 in Hapcheon.

The big sword, with the inlaid pattern, refers to an inlaid sword which is decorated with a gold and silver pattern. This kind of sword was excavated in several sites, including the Okjeon Tumulus No. 70 in Hapcheon and the Wolsan-ri Tumulus No. M1-A in Namwon.

The big sword discovered in the Jisan-dong Tumulus No. 32NE-1 is the most noteworthy among big swords. This sword was decorated with dragon and Chinese ornaments and was inlaid with the arabesque pattern.
