Flint

Flint is a mineral obtained from gravel.

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

Drops
When a player holds an emerald, some fletcher villagers hold flint. If the fletcher is killed while holding the flint, there is an 8.5% chance of dropping 10 flint. The percentage is increased by Looting.
