I don't use poles, and I don't use a stove, and I can get by without a knife. I actually have a small knife that disguises as a single key.

I guess the questionable? items I would bring are:
- folding mini scissors
- a saw composed of a single wire and plastic loops on the ends
- a multitool that folds to 2" long and has pliers and 4 screwdrivers
- small bic lighter
- a micro bottle opener
- a micro wine bottle opener

...but I could make due without all of these things, or buy something inexpensive on the other end. That would be my preference. Actually, my preference would be to do away with TSA bag check. But that's not up to me, unfortunately. If you travel internationally, they may have different opinions of what can and can't go. For example, a set of mini screwdrivers that was just the thing the official may have needed.
