The Infinity Set

The set includes four pieces:
Cantor fork :: now you can pin a single kiwi seed. Twice in a row.
Recursive spoon :: it will never let you spill a drop of soup. Ever.
Koch knife :: to delicately cut hair-thin slices out of an egg. A raw egg.
The Infinity Set :: the set includes itself. As a subset.

One keyword is “contest” so I don’t know if this is simply an artistic concept or a product that will appeal to the geek crowd. I want to use the Koch knife to cut a Möbius strip of bacon.
