Not to hijack this thread but I want to remind everyone of more alternatives in the area of firestarters .

I got a few (free) flint strikers like this one



... as well as a ton of spare flints.

I stashed them in several of my kits.

Although this striker is considerably larger than a sparklite and such, but it can be included in most kits (except Altoids can) like a Maxpedition pocket organizer or larger. You can put it and fill the spaces between its arms with other stuff.

Oh, I removed the cup and exposed the striker surface for better contact with tinder. The shower of sparks is not that bad and replacing flints is not difficult either.
