Abstract : Lots of lithic tools are present in Metal Ages, but few are studied. In metal production, they are especially constitued by strike supports, abrasives, burnishers, sharpening tools and crushing tools. A part of them are in metal ( strike supports) or in ceramic (abrasives, sharpening tools). Contemporary forms of these tools are too different to permit a dierct comparison. It is necessary to work on the function of the tools, deduced from the analysis of these structure. Strike supports used for metal working are easily identifiable. They allow to reproduce more or less precisely the objects that they were fabricated with. Abrasives are difficult to relate to a material, but the traces of use are characteristic of the profile of the objects. Burnishers are characteristic of metal working, especially sheet metal. The sharpening tools are mainly designed for the maintenance of the blades, but it is possible to indentify some of the tools used for edging.Ê The crushing tools are also used for cooking. But we can distinguish the models used for grinding materials (earth, degreaser). The study of the stone also helps reconstitute the sources of axes of trade and exploitation of the territory.
