The English word 'flint' can refer to the hard stone used to start fires, a piece of this stone, or the sparking component in lighters. This guide covers how to express these meanings naturally in Japanese.
Referring to flint as a type of hard stone, often used historically to make tools or start fires.
Literally 'fire-striking stone', this is the standard term for flint used with a steel to create sparks. It can also refer to the material itself.

Same word as for the material, but context makes it clear you mean a piece. Commonly used in historical or camping settings.

In most everyday situations, 'flint' refers to the lighter component. Use ライターの火打ち石 or simply フリント. For historical or camping contexts, 火打ち石 is the go-to word.
火打ち石 specifically means flint used for fire-starting. For generic hard stones like chert, use チャート (chāto) or 角岩 (かくがん).
