Crafting Items for lvl 55

[BlueMagma]

So I know you all have probably seen that Farrow the Forger in BS has recipes for crafting your pink lvl 51 loot to pink lvl 55 gear. I was looking at some of the items in the recipes but saw some items like "Superior Blade" and couldn't find where to make or get that type of item. What do you guys know so far about crafting? Where can i find these types of items?

You get those from the daily quests.
