Fine-grained gray to green-gray material shows stepped flake scars and narrow retouched edges. Brown iron-stained veining appears near the base and the piece tapers to a pointed tip opposite a slightly rounded base.Keywords: stone blade, biface, leaf-shaped, flaked tool, hand-flaked, gray-green stone, knife preform, thin profile, 4 1/8 in
