Some good comments already made.

My Dad and I can't decide between a Cooking Pot and a Fero Rod - what do you guys think regarding other suggestions or the ones mentioned.
I forgot to mention that it has to fit in his pocket !!!!
Fit in his pocket: a very real consideration, because he probably would
not have it on him otherwise. And if it were too bulky, it might impede an
escape from a small plane.
Also consider the more general case, of hiking or air travel. A large (strong)
pot could cause a
focused impact to the body, which could break bones.
The small rectangular shallow aluminum pots might collapse and would spread
the force of impact over a wider area.
A Fire-steel is compact and easy to carry; not likely to be left behind.
Might be taken away on a commercial flight that connects to a smaller
air carrier. You could keep an extra one in luggage while on the big
airplanes, then transfer to your pocket later; fire-steels are cheap.
Clothing is a complex issue.
It will not fit in a pocket, but still worth a small comment.
Synthetic fleece garments are very light and I always carry extra in my pack;
a pack full of fleece would also cushion a fall that I might take.
I also have some wool, so don't anybody start the wool vs fleece war.
