I use a pizza cutter every day. No, I don't eat pizza everyday. I use it to cut sandwiches, slices of cheese and lunchmeat, and most often pasta. A pizza cutter cuts food much faster than a knife or than a sideways fork. I can cut a plate of spaghetti or penne in seconds. We all know that a hungry baby/toddler/preschooler is not in the mood to wait. So the faster you get the food to them, the better. The best benefit is that you can do it one handed! We all know that parents of young kids live life one handed. Try it.
