or chalcedony. The sharp edge of the flint is used to violently strike the fire steel at an acute angle in order to cleave or shave off small particles of metal. The pyrophoricity of the steel results in the shavings oxidising in the air. The molten, oxidising sparks then ignite tinder. The tinder is best held next to the flint while the steel striker is quickly slid down against the flint, casting sparks into the tinder.
