aa Blade triangular, corner-notched, length 1¼ times
the width, base generally convex, expanding, often
just slightly narrower than blade. Largest 1⅛ ×
½, smallest ⅝ × ½ inches. Points of this type are
generally much lighter and thinner than those
above, (Fig. 26).
bb Blade triangular, edges either convex or concave,
specimen’s length generally twice width, almost
all serrated, stems usually straight, generally
½ width or less. Largest 1 × ½, smallest ¾ × ⅝
inches. A variation of this type is less long
in relation to width, but has its base located
a-centrally. Careful examination reveals no
differential of wear on the sides such as would
be expected if they were used as knives. (Fig. 26).
cc These points are located morphologically between
types aa and bb and do not fit into either category.
Largest 1¼ × ⅜, smallest ⅝ × ½ inches, (Fig. 27).
