Use-Wear Analysis

Use wear typically occurs at high points on the edge and shows characteristic polishes and striations. Post-depositional damage (trampling, weathering) tends to be random, affects all parts of the tool equally, and lacks the distinctive patterns associated with specific materials. Careful observation under magnification can usually distinguish them, though heavily altered tools may be problematic.

Yes, significantly. Obsidian, flint, and other cryptocrystalline stones produce characteristic wear patterns that differ from coarse-grained stones. Edge geometry and sharpness also affect wear formation. Experimental reference collections should use the same or similar stone types as archaeological specimens for valid comparisons.

Yes, though the distinction can be subtle. Meat-cutting produces relatively smooth polishes with linear striations. Bone-cutting produces coarser damage, including step fractures and different polish morphology. Experienced analysts can make this distinction, though classification can be uncertain in some cases.

Hafting (attachment to a handle or shaft) implies that the tool was used for a specific, intensive task rather than multipurpose work. Hafting evidence combined with wear analysis can reveal behavioral information about tool use, maintenance, and replacement patterns.

Experimental tools created with known materials and uses provide a reference library of wear patterns. When archaeological tool wear is compared to experimental references, analysts can assign probable functions more confidently. Large, diverse reference collections covering multiple materials and techniques are necessary for robust interpretations.
