Use-Wear Analysis and Obsidian

Investigation of a technique for the functional analysis of obsidian tools. Experiments show that use-action and use-wear can be interpreted, and with what limitations. Residues play an important role as they are more easily seen on obsidian than flint. Discussion assesses wear formation theories and the role of functional information within archaeology. The technique is applied to a group of lunates from a Bronze Age site in Sardinia.
