I have a nice little fire-starting kit that comprises a ferro rod, a hacksaw blade, and a QuickTab, held together by being forced into a plastic tube. The hacksaw blade can also be used to cut metal etc (I've seen the film Saw) and the tube can help exploit slight sources of water.

I also have a simple home-made lanyard in the coin section of my wallet. It's a loop of paracord inner thread, with a clip attached. The clip came with my torch, but it can attach to anything I don't want to lose.

I also have a lot of other stuff, whistle etc, that should not be at all unusual for this forum.
