A ceremonial bronze dagger-axe. These ancient weapons were called a ko or ge. Its dagger shaped blade was attached to a long pole, or haft, allowing it to be swung and thrust in battle. The dagger-axe was used in ancient China from the Shang through the Han dynasties, when it was gradually replaced by the Chinese halberd, or ji.
Normally only the head of dagger-axes are excavated as the haft has decomposed or been removed. Jade ceremonial forms of the dagger-axe have been found in the tombs of nobility, where they possibly served as symbols of authority, power, or protection.
From catalog card: "Fragmentary; lower part of blade missing. Rectangular tang with single round perforation. Ornately embossed and incised deoration which is identical on both faces."
