An item, that I have with me most of the time, is a multitool (Gerber, SOG, Leatherman, whatever. My tool of choice is a Leatherman Wave II, but this is a question of personal preference. Any model would be good to have.). These handy tools can be of big value in everyday life. If you don't have one (or don't want to carry it with you on your belt) at least a Swiss Army Knife/Pocket knife, with a blade, screwdriver, small scissors and the like should be there.
A lighter or some matches are also very useful.
And if you have a multitool or pocket knife and some matches, you can easily make your own toothpicks
