ENThis paper deals with large bifacial flint points, i.e. daggers and spearheads, in Lithuania during the Late Neolithic Early Bronze Age. 13 find places of such artefacts were registered in Lithuania. Find places, contexts, raw material and forms of these tools were examined. Highly diverse origins of flint daggers and spearheads found in Lithuania were suggested. It emerged that the artefacts came from the Upper Volga, Volhynia and south Scandinavia. Some evidence of local production of large bifaces were identified near flint outcrops in the Upper Nemunas. An attempt to explain strikingly different production scales and number of daggers in south Scandinavia and the Upper Nemunas basin was made, and a role of social factors responsible for that was emphasized.
