Bone Pickaxe

The Bone Pickaxe is a pickaxe that is capable of mining all ores up to Meteorite. It has a 2% (1/50) chance of being dropped by Undead Miners, which are an uncommon enemy 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 Tungsten Pickaxe, allowing it to mine Meteorite and destroy Dirt Blocks in a single hit. This makes it the fastest pickaxe for mining weak blocks, such as dirt and snow, until Hardmode. The drawback is that it is unable to mine anything stronger than Demonite or Crimtane Ore, and still requires two hits to mine Stone.

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 an enemy. This, along with the low drop chance and spawn chance of Undead Miners, makes it quite a valuable find.
