What tools would straighten the horn out?

Toss it in the garbage and buy an identical one at a music store.

If you cant find a replacement, just wrap it with duct tape and tell the
parents a drunken redneck in a rolled over pickup truck, stole it, and
you had to beat the guy over the head with it to get it back.
