A friend told me that he had a Notched Pickaxe what will give you smithing levels if you mine so I wanted to know how I could get it.
It's found at the top of Throat of the World. You need to do the main quest to get access. At the top is the Notched Pickaxe which Fortify's Smithing by 5 points. It's rather a reference to Notch, creater of Minecraft and co-founder of Mojang, or 2 mountain climbers who got lost and people found evidence of there whereabouts by finding a mark.
