Imo the Mg blocks are awesome in some conditions. High wind makes them useless for other than a flint. I edc a disposable lighter. A DJeep when I can find them, a Bic when I can't. I have trusted strike-anywhere matches for years to light my grill, and have carried them into the brush also. I found out the hard way to dip the tips in wax, even ones that are in a match-safe.
Do you know where your towel is?
Don't Panic!
I have an extra.
