Flint

Flint is an expendable object found by quarrying Gravel. You can find flint in Gravel approximately 20% of the time. Some players have realised the ability to make stacks of unwanted Gravel then powermine them in the hope that they can gather more flints. Of course this reduces their stash of gravel, but they benefit from the increase in this uncommon crafting material.

Flint is used when crafting arrows, and Flint and Steel.

Flint has the appearance somewhat like coal, but they are very different from each other. Flint is lighter in color than coal is, and it is facing the opposite direction coal is. Flint and steel is treated like a tool, and looses durability after lighting fires. Arrows come in sets of 4 when creating them.
