I'd be real interested. Although I'm out of work (again) and I don't have enough time to use the toys that I already have.
I went to wally world, as I haven't been out of the house in 3 days due to a Final I have in a class tomorrow, and looked at tow balls. They would work, but you would have to figure out how to anneal them.
BTW, someone bought a tow ball, used it, and then returned it. You could tell cause all the chrome was missing from where it had been worn off in use. Some people really blow my mind as to how cheap they are.
That being said.
One of these days I'm going to get a special made something or other from Coal Creek Forge.
Axe, spike hawk, spontoon hawk, ball mace, or a Tomahawk... something or other.
