Great advice, all.
I carry a carbon steel blade and a ferrous rod as a back up to other fire starting items. Stainless will not “throw a spark”. I also carry a Gerber compact saw that stays retracted in the handle until you unlock it and extend it out. Little weight but great capability for cutting small dried branches for starting a fire. A set of Mechanic work gloves. I prefer one of the Energizer head lamps than a handheld light, but its personal preference. A few yards of paracord takes up almost no room but can come in handy tying out your poncho for a hasty shelter. I also use paracord for my boot laces to use in a pinch. A Sierra cup (stainless steel) and a few light packages of tea, instant soup, etc. will be comforting while awaiting rescue.
