The best thing that I have done is made a paracord lanyard that I can slip around my neck so that no matter what happens it is with me. It includes:
1. Paracord lanyard (approx. 15' of cordage)
1. A top quality magnesium fire starter.
2. Very small AAA flashlight
3. P38 can opener
5. Small keychain type compass
6. Small neck knife in kydex sheath
