| Summary: | Baltic erratic flint is one of the most important stone raw materials used in the area of the Polish lowlands. Since its first description published in 1920 by Stefan Krukowski, generations of researchers continue to investigate the topic through studies on the characteristics of this raw material as well as processing successive collections of artefacts made of this flint. In this paper special attention is drawn to production strategy based on this type of raw material typical for Mesolithic inventories. It involves the use of natural flint chunks resulting from shattering of frost weathered concretions. With respect to the materials recovered from the 7 in Dobryń Mały site, it is reflected mainly in the production of core tools. However, to a much lesser extent, it is also present in the process of raw material selection for the production of blade and flake blanks.
