The earlier Eva I form has a long clearly defined straight or contracting short stem which may be equal in length or longer than the barbs. On the latter Eva II type, the barbs may extend below the base of the stem, and the stem is diminished in size and is rounded and contracting and is rarely ground. The Eva's barbs vary from squared, which show the corner of the preform blank, to pointed, and on the Eva II specimens the barbs may even be longer than the stem. The notches oftentimes show circular hertzian cone flake scars at the terminus of the notch. The notch is then often retouched with finer pressure flaking scars.
Early examples can show parallel flaking scars.
The stem on the Eva is rather small on both types, considering the overall blade dimensions. All edges of the stem on the Eva I type are basically straight and the basal edge is usually thinned and can be occasionally ground. On the Eva II type the stem is smaller, and contracting or rounded in outline. The blade shape on both types is biconvex or almost flat in cross section. The Eva point appears to have a localized distribution only within the Tennessee Valley and in fact Kneberg reportied in 1956 that the Eva is seldom found outside the western half of Tennessee.
