I won't assume anything, so I'll say...

1. Fixed blade, 5 inch blade (DMDC would be my choice!)
2. Strikeforce firesteel (has tinder in the case!)
3. Bandanna (or Shemagh).
4. Water filter bottle, like this one.
5. 100 ft. of paracord.
6. My 3m by 3m DD Hammocks tarp.
7. Head lamp (Black Diamond).

That's tough, I usually bring 20 lbs of gear on a day hike! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
