Hard to tell by the pic but i believe the black plastic piece is used to hold rebar in the middle of concrete when you pour concrete. Very handy to have if you are in the concrete business! The roll of metal wire would lay on top of the rebar for reinforcement of the concrete.
The other thing looks like a bic lighter.
When you pour a slab you would have a grid of about every 1 to 2 feet squares of rebar.
Not a gold mine you found but handy none the less!
