Previously I briefly mentioned how to start a fire with a ferrocerium rod. You can see the post here. These days many people incorrectly refer to that method as “flint and steel”. The reality is that the ferrocerium rod is a modern fire-making implement. The true flint and steel method has been around for millennia and works in a slightly different way.
When using a ferrocerium rod to make sparks, the striker actually shaves off pieces from the rod, which then heat up into sparks. With the flint and steel method, the flint actually shaves off pieces from the metal, which then oxidize and create sparks. These sparks are much duller, and require a very fine tinder to catch.
The overall fire starting method with fling and steel will be very similar to that with a ferrocerium rod-you will simply need an extra step with a very fine tinder to catch the initial spark.
The tools required for the task are very basic. They consist of a piece of sharp flint, a carbon steel striker (or the spine of a carbon steel knife), and the extra fine tinder.
Your basic tinder bundle for the fire will look very much like that for the ferrocerium rod fire. You will need some finely shredded grass or a fine fiber like cotton, scraped birch bark, or cattail pollen, gradually moving to courser materials. Before the spark or ember can reach that tinder bundle however, you will require an extra tinder. The faint sparks from the flint and steel will not ignite simple cotton or birch bark shavings. What you need is a specially prepared, extra fine tinder to catch the initial spark. There are several different materials from which it can be made, but the easiest method is to just char some plant material. A piece of charcoal will work fine, so will charred cattail pollen.
IMPORTANT-the material has to be charred, not burnt. To char the material, it has to be heated without igniting. This happen naturally with charcoal from the inner core of the wood, but with finer materials, you will need a metal container (or another method of excluding the flame) in which to place the material before tossing it on the fire. The Altoids tin you see above does the job well. You do not need to make any holes in it; just place the material inside, close it, and place it on the fire. It is done when all the material has turned black. The easiest material to use for this is cotton cloth. This creates a tinder that is easier to manipulate when done. A thick piece of denim works the best, but so will any cotton fabric. This is often referred to as charcloth.
Once you have the charcloth, take a small amount and place it on top of your piece of flint. Hold them in one hand, and using the metal striker, strike the edge of the flint in a downward motion.
Sparks will fly, and hopefully one will end up on top of the charcloth. This should take one or two strikes.
At this point, there is no rush. The charcloth will glow for a while. Take your tinder bundle and place it inside. Now begin blowing until you have a flame.
It is a very simple method, as long as you have prepared tinder. That is why in that Altoids tin a carry the flint, steel striker and some charcloth.
There are some other items you may consider. In the picture below you see a nice brass container of similar size to an Altoid tin and a tinder tube.
The container is just a nice container. The tinder tube however has a purpose. It serves to replace the charcloth. The tinder tube is nothing more than a cotton rope in a small brass tube. You have to initially ignite the end of the rope and then put it out. This will char it. You can then use that end in the same way as the charloth. Place it on top of the flint, and wait for a spark to land on it. Put the end in your tinder bundle and blow it to flame. Once done, pull the rope inside the tube, and the ember will go out. It works well, but I find it harder to ignite the tinder bundle with this method than simple charcloth because the whole time you are trying to make sure you can withdraw the tube when the flame catches. That is why I don’t use this method, but you may like it.
