Body-blade haft frag; roughly triangular; both faces ground and polished; unifacially beveled blade edge, opposite blade margin slightly rounded; medial snap; rounded blade-lateral corner; lateral edge chipped and ground; tool back flattened and ground; blade edge has light use-damage micro-chipping

stemmed point-biface; convex base (lightly polished/ground), straight stem, lightly shouldered, excurvate margins, flattened x-section; flat, unpolished surface, slightly-invasive edge chipping; medial-distal edges exhibit edge retouch-poss from use; knife like

GSK (production failure? to be refurbished?), semi-lunar shape (long straight blade edge, curvilinear hafting edge and lateral sides); one surface ground and polished, opposite surface exhibits localized areas of grinding and polishing (near haft and near blade and lateral side intersection); uneven body thickness--one side roughly 2mm, opposite side roughly 4mm thick; bifacially crude bifacial beveling in localized area on lateral side (blade edge appears slightly rounded); opposite side-blade edge mostly missing (fractured); poss production failure; poss diagonally snapped (orginally much larger GSK) and to be refurbished?
