Flint and Steel

Flint and steel is a tool used to place fire.

Natural generation
Nether fortresses chests may contain flint and steel.

Usage
When used with right-click on top of a solid, fully opaque block or on the sides of a flammable block, flint and steel places fire in the air block directly adjacent to the surface on which it is used. In both Survival and Creative using (right-clicking) flint and steel on TNT will set it off. Flint and steel has 65 uses. When right-clicked to place fire, a point of durability is drained whether or not the surface it is used on is correct for the placement of fire. It also can be used to light a Nether Portal.

The fire-starting ability of Flint and Steel makes it a versatile tool and weapon. Despite the reduction of its spread, fire can still be useful for some clearing jobs. It has the advantage of working on its own while the player can do something else productive.

Flint and steel can also be used to set off the detonation sequence on Creepers.

Trivia

 * In Adventure mode, flint and steel cannot light fires, nor can it ignite Nether portals. However, it can still ignite TNT.
 * If you right-click with Flint and Steel on a transparent block such as glass, or a block which is underwater, it will not start a fire but still consume durability.
 * Flint and steel can be enchanted, but only by using an enchanted book and an anvil. The only enchantment that can get is unbreaking I, II or III.
