Editing Flint (section)

====Comparison with ferrocerium====

Flint and steel used to strike sparks were superseded in the 20th century by [[ferrocerium]] (sometimes referred to as "flint", although not true flint, "[[mischmetal]]", "hot spark", "metal match", or "fire steel"). This human-made material, when scraped with any hard, sharp edge, produces sparks that are much hotter than obtained with natural flint and steel, allowing use of a wider range of tinders. Because it can produce sparks when wet and can start fires when used correctly, ferrocerium is commonly included in [[survival kit]]s. Ferrocerium is used in many cigarette lighters, where it is referred to as "a flint".
