What things do you pack when you go out? something you think only YOU have thought of?

I had something similar to pic related when I was in construction. The pocket clip broke off, and the mirror got scratched up so I tossed that, and now I bring the extendable shaft out for fires. I extend the shaft all the way and blow through it because it helps when I'm trying to start a fire as I can superheat a small pocket of coals.


Not gonna lie, I read about it somewhere.
