I have a PSK in an Altoids tin, thanks to the advice on this forum, and I carry a copy of John Wiseman's SAS Survival Guide (the Collins Gem pocket edition). Since I'm no great shakes at starting fires without matches, and since I'm a non-smoker, I also bought a credit-card Fresnel magnifying glass and stuck it in with my credit cards/driver's license. <br><br>I guess that's the one thing that scares me most about getting lost, is not being able to start a fire when I need to. (I mean, here it is, April in Calgary and we're still getting snow flurries.) So I've been thinking, off and on, about what you could put inside the back cover of a survival manual that would enable you to start a fire IF you somehow managed to get lost with nothing but the SAS Guide in your shirt pocket.<br><br>What I did was to take a small plastic envelope with a zip-lock seal (I think it once held the spare buttons for a new suit). I took some magnesium scrapings and wrapped then in a small piece of tinfoil (actually a foil candy wrapper) and put that inside the mini-ziploc and stapled it to the inside back cover. <br><br>Recently, I took a half-dozen lighter flints and crazy-glued them to a half popsicle stick; I also took a replacement blade from a mini-boxcutter, broke it in half, and wrapped one of the pieces in electrical tape and put those in as well. This makes for a fairly flat package that fits inside the back cover of my pocket survival manual. I figure this provides me with one "last-ditch" shot at starting a fire if everything else goes south. (I'd use all the magnesium scrapings in one shot; I've found in testing that if you don't have a big enough pile, it tends to just flare up and fizzle out without generating enough heat to ignite anything.)<br><br>Any thoughts? Suggestions? Warnings?
