Modern firemaking equipment might be mana from heaven for indigenous peoples but, and it's a BIG but, they are very expensive in terms of their income. It's also a very bad idea for them to become reliant on tools that might "go away" with no warning. It's something that Ray Mears has major issues with. With excellent reason.

I have to disagree with Doug about use in a real emergency. Fire Pistons have been around for a very long time. It's a simple case of practice, practice, practice.
