In several Lower Palaeolithic sites of Southeastern France (i.e. Bois-de-Riquet, Terra Amata), Heavy-Duty-Tools bear use-wears on their cutting edges. The Techno-Morpho-Functional analysis of these pieces allows to propose a mode of action in launched percussion. This hypothesis was test with specific experimental baseline, dedicated to basalt and limestone. First results show a diagnostic of the launched percussive motion higher for limestone than basalt, for which further developments and experiments still need to be performed.
