What to do:
A wire cup brush ought to take the rust off and expose some of the nice, dark metal. Optionally you can file the polls flat because some nimrod was beating the back of it using it as a wedge. Other than that, hang it on your choice of haft (I'd go for about a 30-32" handle for that) - then file the bit so it's thin and sharp.
What not to do:
Make it look pretty and hang it on a wall never to be used.... that's just my personal preference.

Glad you like it, and I can only hope it gets more use than just one truck mishap! I do hope it serves you well, put a lot of time into that piece
