As part of the interdisciplinary research conducted in the settlement microregion in the area of Ulów in central Roztocze (south-east Poland), a complex of late Neolithic Corded Ware Culture barrows was discovered. Apart from numerous ceramic items, grave inventories included flint artefacts, some of which underwent use-wear analysis in order to identify their potential function, and production techniques. This paper presents detailed results of use-wear analysis of arrowheads, blade and flake specimens, and axes discovered in four barrows located at sites 3 and 4 in Ulów. K e y w o r d s: use-wear analysis, flint artefacts, the Neolithic, Corded Ware Culture, Ulów, Roztocze Środkowe mATERIALS AND mEThODS For in-depth use-wear analysis, artefacts from four barrows were selected. The research involved the examination of all flint artefacts from barrows I, II and III at site 3, and barrow II located at site 4. most numerous among these specimens are flint arrowheads, yet retouched blades and axes were also recorded. The sets of these tools were obtained from barrow I at site 3 (six arrowheads, one retouched blade, one axe, and random objects-one arrowhead and one bipolar flake), barrow III at site 3 (one arrowhead, one retouched blade and one axe), and barrow II at site 4 in Ulów (six arrowheads, one retouched blade and two axes). Analysis also included two flakes, two splintered pieces, one burin, one end-scraper, one blade and one chip from barrow II at site 3. The artefacts were made of Cretaceous flint of good quality, most likely Volhynian flint. Unfortunately, in several cases the identification of the raw material was impossible due to the burning of the pieces. Use-wear analysis was conducted with a Nikon LV150 metallographic microscope. The surfaces of artefacts were observed at magnifications of 50×, 100×, and 200×. The flints were cleaned with a detergent in warm water, and acetone. microscopic analysis was carried out in order to find potential use-wear and hafting traces, and to identify the marks made by tools used in the process of knapping. The microscopic traces were interpreted on the basis of the literature (e.g.
