Stone tools are the most common and durable evidence of Middle Paleolithic behavior, but are also among the most enigmatic. They are, obviously, technological artifacts, produced by a set of mechanical processes beginning with raw material acquisition followed by its transformation into blanks and retouched implements, which may be discarded as-is, or undergo one or more episodes of rejuvenation.
At the same time, we can presume that their production was deliberate and goal-directed in the sense that their makers created them to perform one or more tasks. Yet beyond these basic points, Middle Paleolithic stone tools do not lend themselves to easy interpretation. No strong links can be drawn between form and function, at least when the Bordesian typology is used to describe their form.
Maybe Francois Bordes would have called this MTA-Handaxe from the Department Indre-et-Loire in west-central France a sub triangular biface. This artifact has three convex and sharpened margins and a prehensile part seems not to be present. Therefore the tool was probably hafted for use. For sure it has been reworked several times and finally was brought into a unique shape, not compatible with any “type” of common textbooks.
An extended text about reworking late Middle Paleolithic Bifaces can be found in the thesis of Rebecca Wragg-Sykes:
