Middle Paleolithic Chert Biface Hand Axe / Side Scraper

This is a substantial lithic artifact measuring approximately 6 inches by 5 inches, identified as a bifacial hand axe or side scraper. Crafted from chert, the tool exhibits a semi-triangular, robust form with significant thickness at the base to allow for a secure grip during use. The material displays a creamy tan and light brown coloration with visible mineral staining and a weathered patina consistent with long-term environmental exposure in Oklahoma soil. The surface shows evidence of percussion flaking, creating several worked edges, though the specimen appears heavily weathered, which has smoothed the original sharp flake scars. Structurally, the hunk of chert retains its integrity with no major recent fractures, but displays significant ancient micro-chipping along the primary working edge, suggesting heavy use-wear. The craftsmanship reflects Middle Paleolithic technology, prioritizing functional durability over refined aesthetics. The tool lacks maker marks as is typical for prehistoric lithics, but its provenance in Guthrie, OK, provides critical geographical context for North American archaeological study.
