No clue what these are?

The blade of some sort is made of copper/maybe bronze. Definitely has copper in it and the edge of it was sharp. I have no clue what the other is. Any ideas?

Looks like an old weeders sickle.
Here's a new one, but you get the idea.

And the other one looks like a escutcheon for a doorbell.

seems like a couple of pretty good guesses to me! Thank you

Copper and Bronze are not a very hard metal and not a normal one used for cutting edges. Which edge is sharp? Is the thickness of the item flat and uniform? Kinda looks like it has a bend in it from your photo.
