Spork, knoon, fife, knork. Only two of these things exist as far as I know, and I give you two guesses to pick the other one (other than the Spork, of course). It’s the Knork, as you could probably tell from the title and the picture, and it’s a combination knife/fork. I don’t know how well it works, but you can find out with $5. Could be worth every penny for the novelty, and who knows, you might just simplify your utensil selection after trying it out.

“Incorporating critical modifications to the ages-old fork design, the KNORK enables a user to both cut and spear food using only one utensil – and one hand.”
