What's your favorite fire starter?

I personally carry a magnesium/ ferro rod combo and a Bic lighter as part of my standard kit.

The problem that I have with the magnesium is that it can blow away if not really protected from small breezes, however for damp tinder it works great. (Which in about a couple of months will be quite plentifull here.)

The great thing about beating your head against a wall is that it feels so good when you stop.
