Hammer faces would work (def wear goggles!!!). Hit the face of the disposable one with a mixture of hydrogen peroxide, vinegar and salt and wait an hour.

Joining the thread to see where iron balls can be sourced.

		I'd guess exact form wouldn't matter. Wrap a hammer in foil and beat up something rusty.
