Comparison of the edge angles of the working edge and the distal posterior part.
A: Lichtenberg. LiB = bifacial tool, LiU = unifacially shaped tool, LiH = handaxe; B: central Germany. No letter before the number: bifacial tools, U before the number: unfacially shaped tool, H before the number: handaxe. Note the difference between the assemblage of Löbnitz, where the edges are potentially affected by fluvial transport and the edge angles of the excavated assemblage of Pouch and some in situ finds from Goitzsche.
