Bone Pickaxe

The Bone Pickaxe is a pickaxe that is capable of mining all ores up to Meteorite /  Demonite/Crimtane. It has a  /   chance of being dropped by Undead Miners, uncommon enemies found in the Cavern layer. It is tied with the Silver Pickaxe as the fastest pre-Hardmode pickaxe by mining speed, but has higher pickaxe power equal to that of the Gold Pickaxe, allowing it to mine Meteorite and destroy Dirt Blocks in a single hit. It is the fastest pickaxe for mining weak blocks, such as dirt and snow, until Hardmode, although that function is rendered largely obsolete by the.

Trivia

 * The Bone Pickaxe appears to be a counterpart to the Bone Sword, as it is similarly colored and dropped by Skeletons.
 * It is the only pickaxe that can drop from a non-boss enemy. This, along with fast mining speed, the low drop chance and spawn chance of Undead Miners, makes it quite a valuable find.
