There's nothing more satisfying than beating the crap out of an inanimate object. With the Knuckle Pounder, you'd actually get practical use in addition to stress relief.
It's not like most kitchenware, but the Knuckle Pounder certainly serves its purpose as a meat tenderizer. These bad boys are made to be just like a brass knuckle -- but for produce. So instead of hammering away, you slip these on through your fingers and punch that piece of veal until it's ready to be fried up for dinner.
The Knuckle Pounder should add some excitement to prep in the kitchen if music and the company of kids doesn't cut it. I'd just make sure no one takes it out of the home, considering how much more dangerous this weapon just got with the additional ridges.
