If it was Woodland it wouldnt be 10k yrs old. It is a Archaic Knife I do believe. The range will be on the color verses size. Looks to be 3 inches in length. If that helps you any. And yeah there is some value on it. Less than a 100 but probably more than 40 depending on the color.
Not all were hafted some were hand held. Larson put a thread up on some he saw in a museum as how they were done on a handle. Check that thread out it is really interesting. HH everyone
