Fire Horns, items added by the Nether Expansion idea pack, are dropped from Devils and Imps and are used to craft the Pitchfork. 3 are required along with 2 Blaze Rods. They can also be crafted with 1 Netherrack Shard and 1 Blaze Powder. If the player places one in an Item Frame and then uses a Chisel on it, it will turn into a Horn of the Nether.
Fire Horns are small, red, curved items. They appear to be very sharp.
