The Protosteel Iron Sword was a Toa tool formerly belonging to the Toa of Iron Feex. The sword resulted from the transformation from the transformation of Feex's Laser Sickle when he became a Toa. The sword was capable of channeling his Elemental Iron powers. It served as his primary tool in combat, though was later stolen in a battle with a Zeverek bounty hunter named Skorr, who took the blade as a victory trophy. Since then, he has used it as his primary weapon in battles that demand swordplay.
