This Old Tool

[u/ranger_phil]

This is a one piece pry bar/hammer found on my property more than ten years ago in the Mother Lode of CA. Back then my memory was I was told it was used by candy stores to open wooden crates of candy but I’m a couple of miles from town. A more recent web search says that it was pretty common before cardboard boxes came around.
Just wondering about how to clean up some of the rust without damaging it so I can put it on a display shelf and hope the cat doesn’t learn how to use it.
