My .02 here...I would imagine the following list will save your life better than what type of knife or firestarter you took (or didn't take)

A detailed safety contingency plan with someone back home. This plan should entail:
1. A description of your party (how many, who)
2. Make, model, license plate of vehicles
3. The trailhead you parked at
4. A point by point description of your route
5. When you plan to be out.
6. Color and make of your backpack and tent
