inverseRet
Inverse retouch position is the opposite of direct retouch position in that it is formed "when removals start from the dorsal surface" (Tixier 1974, 15). It is more difficult to apply than direct retouch in that the knapper must work from a convex surface on to a flat surface. No traces of it can not be seen from the dorsal face - it is only visible from the ventral surface.
