The steel must be hardened but softer than the flint-like material striking off the spark. [12] Old files, leaf and coil springs, and rusty gardening tools are often repurposed as strikers. Besides flint, other hard, non-porous rocks that can take a sharp edge can be used, such as chert, quartz, agate, jasper or chalcedony. [2]
Sheet Iron tinderboxes. English, 18th and early 19th C. Pocket tinderbox with firesteel and flint. This type was used during the Boer War due to a scarcity of matches. A tinderbox, or patch box, is a container made of wood or metal containing flint, firesteel, and tinder (typically charcloth, but possibly a small quantity of dry, finely divided fibrous matter such as hemp), used together to ...
The steel should be high carbon, non-alloyed, and hardened. Similarly, two pieces of iron pyrite or marcasite when struck together can create sparks. The use of flint in particular became the most common method of producing flames in pre-industrial societies (see also fire striker).
A piece of flint 9–10 cm (3.5–3.9 in) long, weighing 171 grams. Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, [1] [2] categorized as the variety of chert that occurs in chalk or marly limestone. Historically, flint was widely used to make stone tools and start fires.
Ferrocerium is used in fire lighting in conjunction with a striker, similarly to natural flint-and-steel, though ferrocerium takes on the opposite role to the traditional system; instead of a natural flint rock striking tiny iron particles from a firesteel, a striker (which may be in the form of hardened steel wheel) strikes particles of ...

Also called a firesteel. A piece of high-carbon steel used for striking a spark, usually kept in a tinderbox together with flint and tinder. The Fire Triangle Fire Triangle. Main article: Fire Triangle. A simple model that illustrates the three necessary ingredients needed to ignite most fires: heat, fuel, and an oxidizing agent (usually oxygen ...
A spinning steel wheel provided a good stream of sparks when it engaged the flint, and a tinderbox designed to do this was known as a mill. [10] In a modern lighter or firesteel, iron is mixed with cerium and other rare earths to form the alloy ferrocerium. This readily produces sparks when scraped and burns hotter than steel would.
