Being new to this, I read a bunch of info here & elsewhere, then bought a Coghlan's magnesium firestarter & a Swedish Fire-steel Scout.
I collected the lint from the dryer for a week (to my wife's amusement) and mixed it with a liberal gob of Vaseline.

In the warm dry calm environs of my garage, I begin to practise.

Using a sawzall metal blade, I grated off a small pile of magnesium onto a strip of duct-tape.
I tried several square edge blades to create a shower of sparks onto the magnesium.
Lots of sputtering & sizzling, holes melted through the duct-tape, no flame.

Added the lint/vaseline to the mix & tried to fuzz it up to create as much surface area as possible. No flame.
Maybe too much vaseline in the mix (?)

Next tried the fire-steel. Lots of brilliant sparks, no flame.

Next tried the fire-steel with shredded Fire-fly beeswax/cotton tinder. After dozens of tries, managed to get this to ignite.

The fire-steel & mag fire-starter are looking a bit ragged by now.
REALLY glad I did not use a good knife on either the fire-steel or the mag block.

Tried the lint/vaseline tinder with a Bic lighter.
Messy as hell, not really easy to ignite, but once going burns well & long.

Tried the beeswax/cotton tinder with a Bic lighter.
Easier to ignite, far less messy, burns well & long.

Next is to find a place that sells the Djeep lighter, which I read about here.
