Stone Tool Making Techniques: Hard-Hammer retouching and resharpening

The most common stone tool in all times and places—and arguably the most common tool in human history—is the simple sharp-edged flake.  These flake tools were often used just as they were struck from the core, but sometimes the edges were trimmed by flaking to produce a certain shape or edge-angle.  This trimming is called ‘retouching’ by archaeologists, and the resulting tool is a ‘retouched flake’.
