Flint and Steel can be used to burn ground for a while. It is also used to open the nether portal.
To make Flint and Steel, you will need Iron Ore, Flint and Iron ingot using the furnace. Please follow the following steps to make Flint and Steel.
In order to make Flint and Steel, you first need to get at least an iron ore. Equip your stone pickaxe and find some iron ore blocks. You will find some in the underground mining area.
Now the next required item that you will have to get is flint. Use your iron shovel to dig gravel and gather a flint.
Iron ingot using furnace
Now we need to use the furnace to get iron ingots. Go towards the furnace, add coal in the lower box and iron ore in the upper box of it. A single iron ore will give you an iron ingot. Add this iron ingot into your inventory.
Flint and Steel
Now add flint and iron ingot in the adjacent cells of any row or column of the crafting grid to get Flint and Steel in the right side box of the crafting table. Add this item in your “ready to use” stock.
