Notched Pickaxe

The Notched Pickaxe is an item found at the very top of The Throat of the World.

The pickaxe grants the player bonus smithing abilities and when used to attack enemies it inflicts 5 shock damage. The value of the pickaxe is 303/304 septims/coins. The Notched Pickaxe can be disenchanted to learn the "Notched Pickaxe Effect" and can be re-applied to other weapons. Points towards the Smithing Skill increase is permanently capped at 1; the shock damage can be variable as per standard Enchanting rules. Dual-Wielding two enchanted Notched Pickaxes does not increase the smithing bonus over 1.

This item is most likely a reference to the indie creator Markus "Notch" Persson (creator of the indie game Minecraft); while the term "notched" may simply refer to a physical quality of the item, due to its enchantments and its hidden location, it is highly believed to be a Minecraft reference (considering Bethesda has had a lawsuit regarding Notch's game Scrolls with Notch in the past).
