ERROR {{Item infobox}} missing 'type' parameter (See documentation).
The Branding iron is a scrapped Melee weapon. It bears the initials 'TF'. Due to its appearance and theme, it was first thought to have been intended for the Engineer. However, the Branding iron appears to have been originally intended for the Pyro, as within the game_sounds_weapon.txt file, the Fire Axe has the heading "Branding iron". It has also been speculated that this weapon may have had the ability to 'mark' opponents, such as nosy Spies.
