I got one just like it for free when I bought my jalapeno rack. It works like a champ. Try using it to core out Roma tomatoes. It takes out all of the pulp and seeds and leaves nothing but meat. It works really well on apples too.
Mine is a bit older. Has a wooden handle. They do a great job. Got it from the same place as you guys. Check out The Iron Desert and buy one of their nice stainless racks and the shipping doesn't seem so bad.
