Oblique Truncation on a Blade
Engraving tool
Beginning of the Magdalenian

Oblique truncations are [...] on large blades and seem to have been intended to create a robust angle.

Commentary :
At Lascaux, hundreds of tools of various types are present, made on flint flakes and blades of local origin. These tools are largely dominated by engravers.
Broad, thick and fairly elongated blades, are obliquely retouched at one end to create a robust angle on one edge. This angle often bears traces of abrasion, produced by rubbing on a hard material.
These obliquely truncated blades were used by Palaeolithic artists, to carve the limestone walls, of Lascaux Cave.
