Some artifacts from this weekend

[mangum]

Hello all! I found a nice assortment of artifacts this weekend. I assume most are performs or scrapers. I'm not sure about the large piece, any insight would be great. I also found an unusual square stone, any ideas? Thanks for looking & HH!

1st pic the black one I believe is a point the others broken and scrapers. 2nd pic on the right looks to be a broken oval biface or could be a hoe if it is large and still has damage. 3rd and last a very interesting square stone not sure if it is natural or not but still cool. Nice finds

Nice Finds! The item in the second photo looks like a broken knife.
