Working on it! I think the fluffed up twine fibers would go, but I cannot remember seeing anyone try.

Is the rod on one side of the Doan magnesium bar ferrocerium(sp?) and not flint, as I may have erroneously assumed?

How about the strikers on Bic lighters, don't they use flint?

When I was in Los Angeles over the Holiday period I was able to join a small group on a great "survival walk" with Christopher Nyerges (sp?). He had a chunk of rock that I understood was flint, and a handheld steel in the shape like a carabiner that was used as the striker. They put out a lot of sparks when struck properly and easily ignited fine steel wool.
