Pickaxe

Pickaxes are one of the most commonly used tools in the game, being required to mine all ores and many other types of block. Different qualities of pickaxe are required to successfully harvest certain ores and blocks (see below on the Speed and Durability table).

Crafting
Pickaxes are crafted using 2 sticks and 3 units of a tool material:

Speed and Durability
The following table summarizes the speed at which different quality pickaxes perform. Values marked with (*) and highlighted in blue indicate that no resource will be dropped when the block is destroyed by that quality of pickaxe.

Redstone and Obsidian take an unusually long time to harvest because the game does not consider pickaxes to be "good" at mining them; this is probably a bug. The same goes for Furnaces, Stairs and Brick.
