Found and interesting page recently. The usual stuff except for the knives at the end of the article. They look like "side scrapers" but the use wear analysis clearly shows them used as knives for cutting.
Similar artifacts have been given the folk term, "side scraper," by Texas archeologists for much of the 20th century. This technical term has no factual basis with regards to known ethnographic examples. In other words, there is no such formal tool as a side scraper. Expedient flakes were occasionally used to scrape plant materials at Hinds Cave, but these were not hafted tools nor were they used in a consistent way. ---http://www.texasbeyondhistory.net/hinds/artifacts.html
