There are two quests with this name are you looking for:

This quest (either version) grants the Blacksmith who completes it the Armorsmithing specialization.

In this quest, the quester is asked to provide the quest giver

The recipes for these items are provided by a series of quests, the Mithril Order quest chain. While you can bypass this quest chain by simply having someone make the items for you, you miss out on a couple of nice trinkets, and a number of recipes that can only be learned through the quest chain.

Another reason to complete the quest chain is that doing so requires the creation of a number of items using the blacksmithing skill, thus allowing skill increases with a useful end.
