Technological study of the lithic materials from the site Wołkusz 3 in NE Poland. The concept of the preferential blades' production

The article aims to present the results of the technological analysis of the lithic artefacts from the site Wołkusz 3. This comprises a detailed characterisation of one of the two reconstructed flint knapping strategies described as the concept of preferential blades. The Wolkushian culture inventory consisting of almost 3000 pieces was subjected to the analyses. The collection includes the debitage products – cores, flakes and blades, as well as the products of debitage modification – retouched tools and the spalls connected with the process of their production and repairing. The conclusions are based on refitting studies supported by the analyses of the relief of negatives and the morphological attributes.
