Flint, also known as chert, is a type of sedimentary rock that has many uses. It was once commonly used to form rudimentary tools like knives and spear tips. Flint is often used by outdoorsmen to create sparks for a fire when it is struck against hardened steel.
What 2 rocks make a fire?
The type of rock most commonly used in fire starting is flint or any type of rock in the flint family, such as quartz, chert, obsidian, agate or jasper. Other stones also have been known to work. The main criterion is that the rock has a high silica content to be harder than the steel.

Hold a small piece of tinder on top of the rock as you hit it so it will catch a spark and catch on fire. If you cannot find quartz, then look for a similar hard-to-break, smooth rock that breaks with sharp edges and facets. Try different types of stones until you find one that sparks.

What is flint rock?
Flint is a sedimentary rock consisting of microscopic, nearly undetectable (cryptocrystalline) crystals of the mineral quartz (SiO2). Flint is hard (it will scratch steel), but it is also brittle and breaks with a glasslike (conchoidal) fracture that can produce sharp edges.
Can you start a fire with just flint?
Hold the flint down next to the “bed” kind of at an angle so the sparks fall into the “bed.” Take the scraper, or pocket knife, and scrape down the flint towards the “bed.” You should see sparks, if they don’t catch right away, keep scraping.
