The author presents some of his recent results and observations made within the framework of a research project devoted to a comparative typo-chronological analysis of Migration Period knives-daggers in the basin of the Baltic Sea, and to the study of socio-historical tendencies and events marked by the appearance of these artefacts. The intensification of field research in the region in recent years, as well as the rediscovery of parts of the former Prussia-Museum’s collection and regained access to the archives of prewar researchers, has allowed the author to back up the study with an unprecedentedly high number of knife-dagger finds and relevant burial complexes.
