Steel armour set (sk) is an item obtained by exchanging a set of items with a Grand Exchange clerk via their right-click "Exchange" option, followed by the "Sets" tab and clicking on the appropriate item set within the Item Sets interface.
Sets are commonly used to reduce the amount of bank space taken up, which is especially useful for free-to-play players.
