Now isn’t this a primitive and yet useful device to have handy in your home? I cannot recall how many times a perfectly nice cake was ruined as I failed to cut it in even portions, which is why the S-XL Cake Cutter was developed. It has the special feature of cutting cake slices in different sizes according to the age of a person. Who would’ve known that two pieces of plastic would be able to settle disputes over the portion of cake a person should eat? This thing looks viable for a sponge-based cake, but those that are heavy with cream and icing at the top will probably not fare as well.
