R´ esum´ e At the beginning of the 1980s and the associated specification of research on stone artifacts, the focus was increasingly on cores and their reduction. The Levallois concept highlighted by E. Bo´’eda was the cornerstone of this new approach. Building on this and supplementing, numerous concepts have been discussed over the years on how core reduction can take place. In addition to Levallois, discoidal, blade production, the various reduction at edges (burins) or blanks (Kombewa, Kostenki) are to be mentioned. On the basis of well-known core classification systems, this talk will focus on the differences and common features of numerous reduction concepts, as well as add further variants. Here we discuss the dichotomy of volumetric and planimetric reduction variants, as well as the hierarchical structuring and ramification of reduction concepts. The question of whether several reduction concepts can occur in a lithic volume in succession or in parallel is also discussed. The physical parameters of reduction, independent of the producing species, are addressed in order to investigate the extent to which a technological approach barrier exists in the investigation of different epochs (Lower, Middle and Upper Paleolithic). Furthermore, new approaches and its combination for the recognition and analysis of reduction systems are presented and discussed, including Working Stage Analysis, Harris matrices, volume and negative completion, refitting, as well as the possibilities of three-dimensional reconstruction. We endeavor to give an overview of the spectrum of methods available for analyzing lithic reduction strategies and what their significance is.
