Flint

Flint is raw material used primarily 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. A tool with a fortune enchantment will improve the chance of getting flint.

Despite popular belief, it is possible to farm for 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. Flint is only obtainable by mining; making gravel fall onto a non-solid block (e.g. torch, sapling) will not produce flint. Likewise, blowing up gravel with TNT will not produce flint either.

Trivia

 * Breaking gravel with any kind of Fortune III tool drops flint 100% of the time.
 * Gravel mined with a Silk Touch enchanted item will never produce flint under any circumstances.
