The principal aim of the paper is to present technological aspects of Epigravettian flint artifacts form the site Kraków, Spadzista street B+B1, layer 5. On the base of detailed technological analysis 18 cores, 1052 flakes, 399 blades and 48 tools are distinguished. Numerous refittings represent various stages of a progress of technological process and different methods of a core reduction. They also reflect well-preserved flint scatters and are very good source for investigating a complete technological process. The results of work are chaînes opératoires, which demonstrate the specific character of the Epigravettian technology of the assemblage from this workshop.
