What are these things?

[Greenfields]

They have sharp points, one can be un-screwed into basically half, with a threaded end and the other has knurling around the top (guessing a hand tool).

Found in a box of reloading kit.

The long one is excellent for put a gentle champfer inside the mouth of a rifle case.

Could be inserts for a live centre for a little hobby lathe, or similar junk for turning small pipe or tubing on the likes.

I've never seen anything like that used in reloading.
What type of metal are they made of?
