little reshaping of the flake except at one end, where a few extra

classified as drills, but a careful examination of the wear and the 
type of stone material suggests all were used to pry open shells or 
pick out the meat. Originally, those falling into the smaller category 
were called projectile points, but their irregularity, complete absence ° 
of reshaping except at the tip, and their lack of consistent shape or 
symmetry favor the classification as picks.
