I imagine in extremely cold and wet conditions, with wet twigs and nothing else to work with, those two would come in handy (in addition to something capable of producing sparks). Thinking along the lines of current weather conditions in the Northeast, with deep snow. When it's really cold and windy, I don't think I would want to mess with magnesium shavings and whatnot.
Gasoline mixed with some vaseline or cooking oil so that it sticks to the twigs nicely and evaporates slower? Does anything have a lower flash point than gasoline? The only hazard I can think of would be getting it on your hands just before the spark is generated..
It's possible to get calcium carbide shipped, correct? That has to be the neatest fire starting accessory, you drop it in some snow, and voila, acetylene gas!
