Gouges, chisels and cold chisels: these three typological groups were recently introduced by Carlos Aschero (creator of the morphologically-based typological classification commonly used by the archaeological community of Argentina, Chile and Uruguay). Aschero noted the presence in archaeological sites of diverse chronology of instruments with edges that resembled the instruments used in modern carpentry and for which only the brush/wood polisher category existed in their classification. The primary function defined for these instruments would be roughing, to which is added cutting in the case of chisels, with the expectations of working on wood and bone, among other possible materials. Later, this author together with the archaeologist S. Hocsman discussed aspects related to the primary functions and the specific modes of action of each type, in relation to the gestures of use of each one. However, the creation of new typological categories implies not only a macro but also a microscopic characterization that allows to establish differences with other types of instruments. For this reason, we decided to develop an experimental program to apply microscopic-based functional analysis to a set of these three types of instruments in order to discuss our analytical categories along with advances and paradigm shifts in the study of lithic material. The sample under study consists of 96 experimental lithic instruments, which correspond to 32 gouges, 32 chisels and 32 chisels made on two different raw materials, quartz and variety 1 vulcanite. A video of the experience of manufacturing the instruments by the Prof. Aschero and Hocsman, the actions of use of the same during the experience and the first results of the traceological analysis are going to be presented and the categories discussed. la presentación es un video de 450MB que no puede ser subido al sigeva, en este link se puede acceder al canal de You tube donde se encuentra https://www.youtube.com/watch?v=dnH2tCkpI4I
