C.H. Wang, Shang and Zhou Chinese Bronze Weaponry: C.H. Wang Collection, Taipei, 1993, p. 178, mentions that during the Warring States period, the sword was used as a symobl of status and rank. Following the Western Zhou, the swords gradually became longer.
Swords with entirely gilded and also engraved blades such as the present examples are relatively rare. Compare a sword of similar shape with two raised rings dated to the Late Spring and Autumn period, illustrated in C.H. Wang, op. cit., pl. 78; and a sword with flattened circular rim from the Warring States period, op. cit., pl. 97.
