Mid to end of Wrath the Cobalt Triangle Shield was a great way to make money with Blacksmithing. Ore/Bar prices had dropped so low that you could sell the shield directly to the vendor for a profit.

Has anyone found a similar item for Cataclysm, or even Wrath/BC/Vanilla items? I know you can profit off of DE'ing pieces of gear, but I'm more interested in ones that you can sell directly to the vendor for a profit, much like the Obsidian Shuffle.
