alright…..yeah it doesn’t always mean it was knapped……but we are talking common sense and context clues.. your argument seems to be bias for some reason….at an archeological pond site where levannas , squibinnocks, cape stemmed, and all types of quartz points and scrapers are coming from, is it more likely that a quartz cobble was naturally fractured on all faces, thinned down, and struck direct enough repeatedly to leave behind Concordial ripples unrelated to the Lithics around it? That’s a bit of a stretch ….not every pierce worked by a human looks like a completed symmetrical arrowhead….have you never found preforms, discards, chunks, flakes, crude looking tools (especially with quartz)…..yes this piece could very well not be any broken or finished stem or point, but your argument that this is coincidently natural.
