If you love pizza and bad puns, then have I got something for you. It’s a pizza cutter that’s in the shape of pi. Get it? You’re cutting a pie with pi! I told you it was a bad pun. Coming in one of three colors, your Pi Pizza Cutter features a pair of stainless steel blades that ensure your pizza is cut thoroughly on the first pass. I will have to say tha the blades don’t quite look big enough to cut through some thicker pies, so you might want to bear that in mind when picking up this $18 utensil.
