Flint

Flint is a raw material.

Mining
When a block of gravel is mined, there is a 10% chance that a single piece of flint will drop instead of the gravel block. When mined with a Fortune-enchanted tool, this chance is increased to 14% at Fortune I, 25% at Fortune II, and 100% at Fortune III. Gravel mined using a tool with Silk Touch or gravel fallen on non-solid block will never produce flint.

Trading
Flint can also be obtained by trading with fletcher villagers. They will offer 6-10 pieces of flint for 10 blocks of gravel and an emerald.

Unlike other villager trades, trading flint is not renewable due to the trade consuming non-renewable gravel.

Trivia

 * Because of the ability to reset the Nether in the Legacy Console Editions, flint is renewable in them because gravel can be found in the Nether.
