Flint

Flint is raw material used for creating arrows and flint and steel. It is found by mining gravel. When mined, there is a 10% chance that a single unit of flint will drop instead of a gravel block. Flint can also be obtained by trading gravel and emeralds with villagers.

Farming
It is possible to farm flint by placing stacks of gravel and mining the gravel until all gravel has been converted to flint. Any gravel that fails to produce flint at first may be placed down again and re-mined until it does. Using a tool enchanted with Fortune increases the chances that flint drops.

Flint is only obtainable by mining it yourself or exploding the gravel; making gravel fall onto a non-solid block (e.g. torch, sapling) does not produce flint.

Trivia

 * Gravel mined with a Silk Touch enchanted item will never produce flint under any circumstances.
