Goldfield finds

[CliffHanger]

I'd like to know what these things are. All found in the foothills of the Northern Calif. gold country.
The first photo (I don't know if it will be the first or last of the photos) is a worn piece of heavy metal. The inside of the hole is surrounded by steel.
The second photo is a split piece of metal pipe that had what appears to be metal or concrete inside.
Third photo is like a melted rock with melted metal inside.
Fourth and fifth photos are a small knife that is flat on one side it is just over 4 inches long. The top part seems to be missing something. Perhaps a stone or a seal.
The last photo is of some of the other gold field finds I de-rusted such as and old pick head, tobacco can with lid, chisel, old table knife, a very old key that is inside the horse shoe next to the mule shoe, and old Brazil silver spoon, a harmonica read plate and what I think are two different types of broken drill bits. Any info on any of this will be appreciated.

Would your 3rd picture be melted lead? One of my friends found something similar to what you found. He thought someone had melted lead to make bullets or something and dumped the melted lead on the ground and it hardened into that shape.

Hello and thanks for your input. The material is much lighter than lead. A small amount of metal was melted in another substance!?
