What is this tool?

[Gpag]

Can someone tell me what this tool is called and what it is used for? I’m guessing it ha something to do with working with pipe. It’s from my Dad’s shop. He was a carpenter but my grandfather was a pipe fitter and my uncle a plumber.

Interesting. Sure looks like a ball joint to me, but what the heck do I know?

Not a clue. I done all three of those trades.
Balljoint or car part, ??? could be.

I took more photos and tried to take it apart. The barrel tuns and ratchets towards the “handle”, on the right side of the above photo, which is solid metal. It only turns 1 way. The pointed end at the top of the photo unscrews. The other end is hollow. I tried further disassembling this thing but couldn’t loosen the nuts. The upper nut is broken, revealing the threads underneath.
This will end up in scrap recycling but I’d really like to know what the heck it is.

Maybe some type of reamer
