I forget to edit my screenshots all the time, as far as the biface I was thinking like a north blade preform from the first pic but it’s quite a bit more bulky than I expected.
I tried to delete just the photo from my previous post, but it wouldn't let me delete the photo so I deleted the whole post. It's just funny anyway. Nothing compromising... unless of course you were getting ready to knock off a liquor store, rather than go to the grocery.
Mrtodd...Looks like a preform, but could have been used as a scraper. A microscopic view may reveal use wear and that could tell the tale.
nice piece regardless. keep up the good work
