Flint

Flint is raw material used primarily for creating arrows and flint and steel. It is found by mining gravel. There is a 10% chance that a single unit of flint will drop instead of the gravel block. A tool with a fortune enchantment will improve the chance of getting flint. It is possible to farm flint by placing stacks of gravel and mining them down; this is a one-way process, there is no way of turning flint back into gravel.

Trivia

 * It takes 4 1/2 wooden shovels to convert 24 blocks of gravel into flint. Using this result, it should take 12 wooden shovels to convert one stack of gravel into flint.
 * It is not possible to convert gravel to flint by placing a half block underneath it, and allowing gravity to turn the stack into resources.
