The Master smithing tutor (real name-Sani Semiv ) is located in the Lumbridge Mine in the tutorial he does not make any more appearences after the tutorial, and he seems discontinued because of the White knight tutorial being discontinued. This shed is marked with the anvil icon on the minimap. After that he's located south of the west bank in Varrock. He teaches players the basics of Smithing. He appears to be shorter than other human NPCs.
