Flint

Flint is a mineral obtained from gravel.

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 a non-solid block will never produce flint.

Trading
Novice-level Fletcher villagers have a 50%‌ or 2⁄3‌ chance to offer 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.

Natural generation
Flint can be found in 55.8% of village fletcher chests in stacks of 1–3.

Mobs
If the mob Kooky Cookie is killed, she drops 1 Flint.
