IDEA!!A real survival kit IMO should be in a size of a small backpack and should help you survive a few days/hours until rescue arrives. It should contain at least the following:
A bottle of water
A fire starter
Some dry food bars
A sleeping bag
This is a survival kit that will really help you survive, the other kits that are marketed as "survival kits" are more like "gadget kits".
For example, If you dont have water or food what use will be your axe?
