Blacksmiths a crafting profession in Classic WoW，specialize in turning various ore and metals into plate and mail armor, weapons and other items, such as  Arcanite Skeleton Key for opening chests and even  Runed Copper Rod, for  Enchanting.  Blacksmithing can be very challenging to level as gathering materials for higher-end recipes can be very costly. But, the reward in the product that you wield can be very lucrative for you. Blacksmithing is often paired with  Mining, to eliminate or lessen the need to buy materials from the Auction House.
