Popis: Backing techniques represent one of the most relevant technical aspects involved in the manufacturing processes of backed tools. In this paper, we present results of an experimental programme focused on the manufacture of backed points, a kind of tool that has played a key role in Upper Palaeolithic technical systems. In order to identify which retouch techniques are effective to produce backed points, different combinations of retouchers (lithic vs. organic) and force application modes (percussion vs. pressure vs. abrasion) were tested. Through a morphoscopic analysis, it was possible to identify and describe numerous mesoscopic and macroscopic criteria useful for the identification of retouch techniques. The results of this experimental activity were then validated through a series of blind tests. Furthermore, these criteria were applied to an archaeological assemblage of backed points from the Late Epigravettian series of Riparo Tagliente (Verona, North-Eastern Italy). It was thus possible to determine the use of two retouch techniques: soft stone percussion on anvil and pressure by a soft stone retoucher. If percussion on anvil had already been attested in several Late Glacial sites, pressure by soft stone is here identified for the first time in an archaeological context.
