So I have been finding these things along a km of beach in northwestern Ontario. The one is a confirmed arrowhead, the rest are kinda all up in the air
I think we have some folks on here from your area or at least the upper P of Michigan that may be able to help you better than I, but I'll give it a shot.
The long piece is more than likely an Awl and a really nice one. The small spike looking pieces could also be Awls and they could Toggles for Fishing.
The piece just below the large Awl is probably an Arrowpoint.
Not sure about the circular pieces. Could be rings?? The other pieces are probably just fragments of other Awls or Fish Hooks.
Here are some pictures of some Copper Culture pieces I have from Wisconsin. There are 3 small Points, 3 Fish Hooks (ones a Toggle), and an Awl in this tray.
I think the round ones are modern rings like seals but you do have some others that look like the real deal. I saw a round ring in the field yesterday that was modern off a tractor.
Nice pieces. I believe you have several awls a tanged knife, a point and the rest is float copper or refuge from making things. The rings are more modern times. Thanks for sharing! Here is a really ugly socketed spear I found last week and a small conical.
