I tend to keep useful items on my key ring as that is always with me. I've seen others do the same thing but I haven't seen anyone with one of the bottle carriers I have, so I thought I'd post a picture.

The bottle carrier will attach to the top of a disposable bottle of water, e.g. Poland Spring or whatever you can lay your hands on. Other items include a small knife, lighter, compass and LED light.
This will also test whether I can get a picture into one of my posts!
