Flint

Flint is a raw material.

Mining
When 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 will never produce flint.

Trading
Flint can also be obtained by trading with farmer villagers. They will offer 4–5 pieces of flint for 10 blocks of gravel and an emerald.

Trivia

 * Because of the ability to reset the Nether in the Xbox 360 edition, flint is renewable in it because gravel can be found in the nether.
