Gear

The gear was a block that could be placed on walls and grounds, but had no clearly defined or implemented functionality. It is believed that gears were intended to be used in mechanisms, similarly to redstone wire.

Gears are only known to be obtainable through the use of inventory editors and other external tools.

Gears cannot be targeted by the player and thus cannot be destroyed by mining them. If it were possible, they would have a hardness value of 0.5 and a breaking time of 0.75 seconds.
