Huge Ancient Chinese Bronze Ge Axe Halberd 770-476 B.C. Eastern Zhou Dynasty

An authentic ancient Chinese huge bronze Ge (dagger-axe) halberd blade that dates to the Spring and Autumn period (770-476 B.C.), which corresponds roughly to the first half of the Eastern Zhou Dynasty period.
MEASUREMENTS: Overall length: 33 cm (12.99 inches), Height: 14.5 cm (5.71 inches).
CONDITION: Showing the age and usage, thick dark green patina with earthen deposits, tang broken, blade chipped. All of this is an aspect of an ancient bronze combat weapon, considering its age to be over 2500 years old.
NOTE: The Ge is considered the most characteristic weapon of ancient China, having been wielded by warriors during the early Dynasties of Shang, Zhou, and Han. Its use in war was restricted to only this most ancient period of Chinese civilization; as such, its distinctive form has become symbolic of this golden age. The blade was designed as one component of a type of halberd known as a ji (Ÿ), a composite weapon made from a double mounting of the Ge with a mao (spear) set above it on a single pole. This provided a greater versatility in application since a ji-armed warrior could thrust with the spear point and hook or puncture with the dagger-axe blade.
