The dagger-axe () is a type of polearm that was in use from the Longshan culture until the Han dynasty in China. It consists of a dagger-shaped blade, mounted by its tang to a perpendicular wooden shaft. The earliest dagger-axe blades were made of stone. Later versions used bronze. Jade versions were also made for ceremonial use. There is a variant type with a divided two-part head, consisting of the usual straight blade and a scythe-like blade.
