The Oblivion Pickaxe

The Oblivion Pickaxe is a single, extremely powerful endgame tool. It mines faster than any vanilla pickaxe, automatically clears entire veins of common ores, smelts what it mines on the spot. It also has an optional "Void Filter" mode for quickly clearing out junk blocks while tunneling, and no it doesn't clear out ores so you can mine safe without worry.
