What are these for? Iron spikes with loop

Found a box of these in an old attic yesterday.  Not sure what they are.  My first thought was mine shaft hardware, that could be hammered into rock and hang lights or something.

The big piece is about 7in.

Have seen similar to the spike type at top used for rock climbing !! No idea about the other two but your theory sounds good to me !!  Are you in an area where mining was done ??

Have seen some that were used for securing traps (gin traps).

Here is my guess agreeing with mart  Pitons

Thanks guys.  Looks like they are pitons.

That sharp pointed one would be great for driving into barn beams, barn wall, wooden frame wagons or whatever yu needed to tie a rope to or hang something on.
