Uniface, this is my first post but I've been reading this forum for a long time and want to thank you for all of the info you post - I find a lot of uniface items so your info is really appreciated.
I know you said the indentation in your item above is not a spokeshave but I'm a little confused about spokeshaves and hope you, or someone else, can help me. Some say it is a knapped, concave area in a blade or a point but I've seen pics of little uniface tools being called spokeshaves. Are both right? Is it simply the concave (scraping) area in a relic that qualifies it as a spokeshave?
A spokeshave, to my mind at least, is semi-curcular, or at least ovoid in shape. This begins with a square edge and runs essentially straight. They didn't make it that way by accident, I'm sure, but it's hard to imagine what use they had in mind beside scraping something.
You say you find a lot of unifaces. Where are you located ? It's of interest to know. In some parts of the country, uniface tools run all the way through time. In others, they taper off and disappear by the end of the Middle Archaic. In many parts of Pennsylvania, they disappear early on and never re-appear (unless you count Woodland microblades). So location's important.
I'm collecting useful information here as well
Thirty7 -- the smaller one's Hornstone. The larger one is hornstone quality (better than some of it) but without the gloss. Tan and grey with an off-yellow band between them. One of the mystery lithics from around Kentucky somewhere that intrigue me.
Glad you folks are finding this stuff of interest. It fascinates me, & always has.
