This whole thing is so weird to me -- while I was REALLY laid up for about 3 months, I watched 6 survial oriented forums. I saw pencil sharpeners come and go on several of them (Mike -- you with me?)
But there were few actual tests. Hey, try it in your woods. If it works, good. If not, move on to the next mode of fire starting. Cody says 3; I can't really count what Doug says, but it sure is more than one.
