How do you dent a baseball bat?

Answer 1

It depends on the bat, but for an aluminum bat like the Anderson Techzilla, if you hit rubber balls in the batting cage, the bat will dent soon enough.

Answer 2

You buy a new bat. Structural integrity of the bat would suck and the inside of it would be broken

Answer 3

This won't work on dents, but I use a little toothpaste on a wet rag to rub the marks off.
