This is a cool idea.
Not yet, I have fire steel and a piece of hack saw blade, heard some guys talking about making a key fob out of one. Not a bad idea, could wrap it in paracord with some type of loop, away from the wheel. I would go that route. I will get one and check it out.This is a cool idea.
I am just afraid I would lose it. lol
Have you tried one before?
