The chisels and gouges equally merit a special mention.
The chisel (fig. 99) is a kind of quadrangular prism, chipped in a bevel down to the base.

The gouges are hollowed out on one of their faces, so as to act as the tool the name of which has been applied to them.
We next come to some curious instruments, of which we have given designs taken from the specimens in the Museum of Saint-Germain; the purpose they were applied to is still problematical. They are small flakes, or blades, in the shape of a crescent (figs. 100, 101). The inner edge, which was either straight or concave, is usually serrated like a saw; the convex side must have been fixed into a handle; for the traces of the handle may still be detected upon many of them. These instruments were probably made use of as scrapers in the preparation of skins for garments; perhaps, also, they were used as knives or as saws.
