At the Pleistocene-Holocene transition, a very wide-spread phenomenon of ‘ technical globalization’ (Valentin, 2008) is proposed by certain archaeologists, based on strong analogies existing between geographically distant lithic productions ([ Epi-] Laborian, Belloisian, Ahrensburgian or even Swiderian). Therefore, it necessary to develop criteria evaluate actual degree relatedness these diverse traditions, which, nevertheless, differ sometimes in their projectile implements. Do real similarities with regard knapping methods exist, what do they consist of, and indicate as precise characteristics intended blades bladelets ? Moreover, way are intentions distinct from known Late Federmesser-Gruppen (cf.
