That is a picture perfect scraper, the light colored blade in the third photo is a nice one. the bigger dark colored blade is a nice one look's like it might have been resharpened or reworked some, it look's like it might have a bit of a stack on top. What is the round stone on top of the piece of pottery a pecking stone or a grinding stone ? Great fishing sinker it has a nice deep groove on it. Those are some nice finds.
