This antler pressure flaking tool is from North Carolina.  The pressure flaker is from the Wall Site  (31Or11), Orange County, North Carolina, and dates to the Late Woodland period, ca. 400-500 BP.

The Wall Site was a large and significant palisaded village on a bend in the Eno River.  It dates to the Late Woodland period, and was occupied from 400-500 years ago.  This significant site was excavated by archaeologists periodically in the 1930s, 1940s, 1980s, and 2000s, uncovering about one-third of the 1.25 acre village.  Abundant artefacts were recovered along with circular house foundations made of vertical posts and measuring about 25 feet in diameter; special-purpose storage buildings; trash-filled pits; a thick midden; eight burials; and five alignments of the stockade wall that protected the village.  Archaeologists estimate that about 100-150 people occupied the site for less than 20 years, and the stockade was rebuilt increasingly larger as the village expanded.

Pressure flaking involves pressing a tool against the edge of the stone until it breaks and a flake is initiated.  Antler is particularly good for this, as it is soft enough to grip the edge of the stone yet robust enough to resist splintering.  The tool was likely used to make Late Woodland triangular points, such as the Madison/Yadkin point types.  The perforation at one end was probably for a suspension loop.

The artefact is curated in the North Carolina Archaeological Collection, Research Laboratories of Archaeology, University of North Carolina at Chapel Hill, catalog no. 49a110.
