Like the other Brewerton styles, Brewerton Eared-Notched is part of the Laurentian Tradition. It is Late Archaic in age. The blades can be triangular or Lanceolate. Shallow side notching removing the lower blade edge results in tangs or ears that flare out so that the base, mostly concave, sometimes straight, is wider then the blade.
