St. Charles (Dovetail)

8000–6000 BCE, Archaic (Eastern)

The St. Charles or Dovetail point is a large Early Archaic knife and point of the Midwest and Ohio Valley, about 8,000 to 6,000 BCE, prized for its size and its frequent manufacture in colourful Flint Ridge and Wyandotte chert. It is one of the most valuable Archaic types. Caches are known.

Diagnostic traits

Also called Dovetail; broad corner-notched blade with a convex, ground, expanding base and a bevelled edge on resharpened examples.

Identification

Dovetail has a broad blade, corner notches, and a convex, ground, expanding base that resembles a dovetail joint, with alternate bevelling on resharpened pieces; Thebes differs in its squared or key notches and straighter base, and Lost Lake in its narrower barbs and unground base. The base is thinned from below. Hardin has a straight stem.

Reproductions and fakes

Dovetails are heavily faked because of value, usually in heat-treated Flint Ridge or Wyandotte with bevelling that is too neat and a base without grinding. Genuine bevels come from repeated resharpening and are asymmetric. Ultraviolet examination can show modern heat treatment.
