I keep an old Ozark Trail Hobo Tool in my overnight bag. I can't tell you how useful it's been when traveling and ending up at a hotel somewhere getting take out to have an actual knife and fork.

I got a full set of silverware for backpacking that collapses down to about the size of those folding reader glasses (plus a little hard storage case just like the glasses). It’s a spoon, fork, knife, and chopsticks. I think I paid $6 for the set. Not super high quality, since the focus was on weight and utility, but definitely does the job.

I don’t use it much anymore, but it was great for lunch at work, and is good when traveling (staying at hotels and getting takeout - no plastic trash!). I mostly keep it in my overnight backpack so it’s available whenever I’m not home and I can’t forget it.
