This is a compact flint and steel set we call "chisquero" our forefathers used, it's totally wind proof (in fact, the more the wind, the better it works

) still sold in some tobaco shops though i think it will dissapear soon cause people don't use it any more, butane lighters are more practical and don't smell/smoke that bad.
At the upper side you can see a wide tube that holds a cotton fuse (fuse is yellow) it has a spheric metal plug that keeps the integrity of the charred end of the fuse and also works as fuse extinguisher..
Below at it's side is a steel wheel and inside of the thin tube is a spring that pushes a little flint against the steel wheel, wich make the sparks when the wheel is twisted by hand, the bolt at the opposite side is where flints are recharged when worn out, also the bolt regulates spring presure.

How does it works...
Pull out the fuse pulling the spheric plug (as you can see spheric plug is hooked on the fuse) and put the charred end of the fuse in front of the sparks exit.
Then strike the steel wheel so a shower of sparks land on the charred end of the fuse... now you've got a glowing ember suitable for light up a cigarette or start a fire placing it on a tinder nest.
To extingue the fuse just pull it down so the spheric plug shut's the tube and ember goes off due to lack of oxygen.

The older version just has the fuse tube and spheric plug. Sparks where made over the charred end of the fuse with a steel (like a chain link) and a flint stone.
