This article presents the study of a unique artefact in the form of a very large trapezoidal axe-head with rectangular section from Słupów, Lesser Poland, against the background of Eneolithic phenomena occurring in the area. The specimen is in the collection of the Archaeological Museum in Kraków since 1929, but has not been discussed until now. It was made by local communities from flint of the G variety, a raw material exploited by Eneolithic groups in western Lesser Poland. The axe-head from Słupów is one of the largest flint axes to have been discovered on Polish lands. This find provokes a broader discussion of the role of local production of macrolithicfour-sided forms against a wider background.
