Turquoise inlay on bronze was a difficult technique that had already appeared on ornaments during the late Erlitou Culture. The motif of bird seen on the hafting bar of the present blade was a particularly popular one on works of art from the Shang dynasty, as the Shang people believed they were descended from a black bird. Similar ge-halberd blades were excavated from late Shang dynasty tombs, such as an example from the tomb of Fu Hao, consort of King Wu Ding, found at Anyang, Henan province, illustrated in Yinxu Fuhao mui (The Jades from the tomb of Fu Hao at Yinxu), Beijing, 1980, col. pl. 17. Unlike the present example, the jade blade of the Fuhao ge fits into an additional bronze socket inlaid in turquoise with a taotie mask set below the hafting bar. The Fuhao ge is currently on display at the National Museum of China, Beijing (fig. 2).
