A small tin can carry vital equipment for emergency use in a survival situation. I spent £22 with Amazon to get Limitless Equipment's "Survival Kit Mark 1", although you could put one together yourself.
The one I bought contains these 10 items:
- An emergency whistle and fire-striker - the whistle works easily and the fire-striker creates sparks which can ignite a small piece of cotton wool or cotton from a tampon (also included);
- A rough wire which acts as a saw - it has a handle at each end and is useful for cutting wood;
- A compass that can be critical in avoiding moving in the right direction - especially it it is dark or cloudy. Also it's more reliable than using the sun for directional guidance. There is also a pencil and paper supplied, which could be helpful for maps and record-keeping;
- A fishing line with a hook, float and weight. Very useful for catching fish for survival;
- A small torch. At first I thought it wasn't working then realised it had one of those seals you have to peel off before the battery connection can be made;
- A plaster or wound dressing useful in the event of injury, along with a sewing kit, safety pins, cleaning swab and a sterile blade;
- A coffee filter for helping to purify drinking water, along with water purification tablets and rubber bands;
- A condom, useful for carrying water from a stream to a campsite or base;
- Various bits of metal - a copper wire, and paper clips. Also various ties for fixing things and a long string;
- The tin containing all the survival items - which is itself useful for cooking and conveniently includes sachets of sugar and salt. A sheet of silver foil is also included.
