Meat Tenderizer.. why do you taunt me?

So when G. and I were moving into our apartment, I was given many misc. kitchen utensils, by my beloved nana.  In this multitude of utensils there was a meat tenderizer.  Yesterday I decided to make pork chops and thought if maybe I used the tenderizer that the pork chops would be AMAZING.  So I used the tenderizer for a total of four whacks and then rubbed the mixture of spices that I concocted.  After letting that set, I put them in a frying pan on a medium heat and let them cook thoroughly so the were at the right internal temperature.  While the taste was good, the texture that they had was not appetizing.

So the first attempt at the meat tenderizer was not successful...so to searching I go.
