I've been using several on line resources to teach myself how to identify points, but it can be a bit overwelming. I'm pretty sure this is a knife blade. It is 4 7/8" long. What's the name and region for this piece?
Unless you set it down somewhere and lost it before you finished shaping and sharpening it....
I think that a lot of un-notched or un-stemmed point types are actually preforms that were finished to a certain stage and then stored, and never got finished for whatever reason. I do that myself quite often. If you flintknap, you know what your stemmed and notched points look like before you stem or notch them.
In any event, that is a killer piece, and a great find!
