From Pathfinder Wiki
Using flint and steel to light a fire is somewhat difficult. A piece of flint, quartz, jasper, or any hard, non-porous rock can be used as the "flint." The steel should be high-carbon steel, such as found in a knife blade. The flint is used to knock tiny pieces of steel off the knife, and in doing so, raise the temperature of the steel so that it glows red hot. This is the spark. It must be caught (perhaps on a charcloth), moved to the tinder, and then blown on to cause the tinder to ignite. This takes a lot of practice.
