Name this tool N/C

Bought this tool recently and have no idea what it is used for.

Thought it might have been an old hay knife, but the only sharp edge is the end.

My uncle owned it.  He was a TV repair guy.

Removes nails from roofing slate.
Slide up under slate, hook nail, and hammer down near handle to pull or cut off nail.
Older slate roofs usually had copper nails - tool could cut through copper pretty easy

I thought it was a "Slim Jim" tool that is used to unlock cars that have the keys locked in them!

Either that or a tool used to remove copper nails on slate roofing......

I had no idea what it was.

Also works for changing wooden clapboard siding. Slip under siding, hook nail, drive with hammer to break nail.
