I'm sure someone is about to ask those questions about this sandwich cutter from Mom Invented.
Let's get it out in the open. No one needs a device to cut their sandwich into puzzle-shaped pieces. No one.
But it's cute. If you've got kids, it's an easy and innocent way to make food a little more fun without resorting to creating sculptures from pancakes or carving vegetables into cartoon characters. This is something you can do if you have no artistic skills. It takes a second to cut the sandwich and you're done.
There are also cutters that will cut the sandwich on the diagonal, in four triangles, or in a heart-shape. They all remove the crust from the bread, if it's a standard-sized loaf. I thought the puzzle shape was the most interesting, and something that would be annoying to do with a knife. The other shapes might be useful if you need to cut a lot of sandwiches quickly, and you wanted all the pieces exactly the same.

Although I'm not as rabid about unitaskers as some people are, I've got two words for you. Cookie cutter. Think how cool it would be to cut puzzle pieces from different doughs and piece them together to make one big puzzle cookie.
That's what I'll be doing when cookie season arrives.
