I also like that they didn't try to add a knife. If someone's gonna carry their own eating utensil they probably already carry a knife they're happy with. Anyway, I couldn't find one online, nor instructions on how to make one, so I gave it a shot and made a quick version out of wood.
(*I say "fork-spoon" cause this isn't a "spork," which is a spoon with very small tines cut into it. I don't find that sporks work well as a fork or spoon.)
Step 1: The tools I used
Besides switching out individual tools, other ways to make this could include carving it using knives, or cutting the handles off a regular fork and spoon and welding the tops together.
