8. The Steel Steps
Again, unless it's a no disqualification match, this is is probably not the best item to use.
In a straight up wrestling match, if you're caught attempting reconstructive surgery with steel steps, you're likely not going to win. Referees are weird like that.
But when it's allowed, the use of the steps is a definite game changer in any match. Whether they're heaved at someone's skull, or a wrestler takes a hard slam onto them, they can spell the end of any bout.
