Drax

The Hamdrax is an all-in-one tool made using every chainsaw, drill, and several souls. It can break almost all bricks, walls, and furnitures in one hit.

Though the most powerful tool in the game as of 1.1, it may be a bother if one breaks anything unexpectedly since the Hamdrax breaks everything, including Demon Altars. (Like the Pwnhammer, this only works after Wall of Flesh is killed in a world.) Getting this tool is very tedious since you'd have needed to kill all 3 new bosses to get this. Meaning that you will have to survive killing Skeletron Prime, The Twins and The Destroyer at least once to get this and each soul is ONLY dropped by one of the bosses.

Trivia

 * Hamdrax is a portmanteau of words hammer, drill and axe, because it can perform the actions of all three.
 * Although the Pwnhammer is not included in the crafting ingredients (or any hammer for that matter), the Hamdrax can still destroy Demon Altars.
