This kit cuts things downs to the real basics; fire and water. For me fire is key, it provides warmth, signals rescue and keeps the boogeyman at a distance, so I tripled up on it. A small disposable lighter, a fire steel with attached magnesium and some artificial tinder. There will be fire, even in the wet. And I still have room for water purification and a couple of goodies. For water I decided on a method that a friend of mine showed me. I got a hold of small dropper bottles that used to contain breath freshener. Cleaned up they make an awesome container for household bleach. 2 drops per liter and you have potable water in 30 min. No fuss, no muss, no bother. I have not done the math yet but I figure that I could get a couple of easy gallons from the little dropper bottles. To the fire and water I added a very small compass, and just in case, and because it fit and a p38 can opener, why tear up your knife when making a cup for your bush tea out of a discarded soup/beer can? All this fits in a little plastic case the size and shape of a pill bottle. I wrapped the bottle in 3 feet of duct tape, because well, you don’t really need to explain duct tape. There is no excuse not to keep in on your person. Its light and you don’t need much in the way of training to use any or it! I find that dropping this in my pocket has become second nature. Let me know your thoughts!
