Generally slender blade with parallel or slightly excurvate edges

Some types, such as the so-called Ross County type, may be relatively broad

One or more "flutes", a distinctive flake struck from the base toward the tip on one or both faces that flattens the point, making it fit more snugly on a spear shaft

Length of flutes generally about one-third to one-half the total length of the specimen

Generally well made, often from high-quality flint

Flattened to biconvex in cross section

Base concave; basal edge usually ground smooth

Blade edges ground smooth from the base for a distance comparable to the length of the flute

Size: 1 to 6 inches in length; many range between 2 and 4 inches long

Early Paleoindian,ca. 9500-8500 BC
