As stated, im sitting at 513 Blacksmithing and all my items are green. I'm trying to find a recipe that will take me the rest of the way to 525. Any suggestions?

Horde players can find Kuldar Steeltooth at Dragonmaw Port in Twilight Highlands. Alliance players can find Brundall Chiselgut at Highbank.
