This survival kit is the product of many years spent in third world countries as both a soldier and contractor. I have carried, and used more then once, this kit in Central and South America, Africa, and Afghanistan. It fits nicely in a small pouch on my vest.
Step 1: Fire
You should always carry at least three (3) ways to start a fire. I carry storm matches in an old travel size Tylenol bottle that I super glued the striker to and covered in duct tape. a mini Bic lighter, and a magnesium block with flint. I have "fire sticks" that I got at Wal-Mart years ago and tinder balls I made by soaking cotton balls in vasiline petrolium jelly.
Step 2: Light / Signaling
For lighting and signaling I carry a AAA duel beam LED flash light. It can produce a 125 lumen white light that has about a 75 ft range or a 30 lumen red light for tactical environments. Two (2) 9 hour emergency candles can be used for light, heat, or to help get a fire going and spare batteries for the flash light.
Step 3: Fishing Kit
It seems that every survival kit has some kind of fishing kit in it and mine is no different. For years I carried regular monofilament line, in recent years stronger, more durable lines have come on the market. A few years ago I switched out monofilament for a braided line. I use a 50lb test line that has a diameter of standard 6lb monofilament line. I have an assortment of grubs, jig heads, and spinner baits as well as various hooks and weights. Snap swivels, barrel swivels, and plastic beads finish out the fishing kit.
Step 4: Snares
I use 75lb test, black nylon coated, stainless fising wire for snare wires. You can get the wire at most Wal-Mart or K-Mart stores for under $3. I have used snares made from this wire to take game as large as racoons and most recently while teaching survival skills to my kids to take a prairie dog in our pasture.
