🔎 UNIDENTIFIED Can anyone identify any of these?

Found in Central PA. The triangle piece caught my eye just because of the bend at the end like it was hit, it rang up like copper/brass.

The knife looking object has a reddish color towards one side and iron on the other side.

And the last rock looking thing, might just be a rock lol but the one side didn't look natural to me.

Some other items I found in the spot previously was a 1848 Large Cent and a pewter spoon bowl.

Any help is appreciated, thanks!

I see odd shapes and ragged edges characteristic of cast iron cooking pot parts. The iron is brittle and breaks up from cultivation of the soil. I've found a large number of such pieces. They can indicate a good, old site, so keep looking around.
