Stone Tool Making Techniques: Hard-Hammer core reduction

Core reduction often involved striking flakes directly from a core to produce flake tools for immediate use,  or flake blanks for further reduction.  If a stone hammer is used for this, the technique is referred to as hard-hammer direct percussion.
