Feuerstein vs Flint
flint
'Flint' and 'Feuerstein' mean the same hard rock. Both words fit when talking about Stone Age tools or about sparks for making fire. 'Feuerstein' is usually easier to understand in everyday language because the word directly reminds you of fire. 'Flint' is a bit more technical or shorter and also appears in factual texts. In terms of meaning, there is no important difference here.
Feuerstein
Mit einem Feuerstein und einem Stück Stahl schlug Tom kleine Funken.
With a piece of flint and a piece of steel, Tom struck small sparks.
Flint
