The flint daggers of late Neolithic period from Denmark are considered some of the most technically complex stone tools in the world. They were instrumental to farming societies at the end of the third millennium BC. At the time, many types of flint tools were essential to everyday survival, but daggers were also considered as prestige objects that could signal status. Men were often buried with daggers by their waist.
The tools were made with the so-called pressure-flaking technique, which involved removing small flakes of lint with a sharp tool. The production of lanceolate-shaped bifacial flint daggers marks the transition from Stone Age to Bronze Age in Denmark; they were eventually replaced with metal arrowheads.
