Ace of Spades

You are carrying one.
Finely honed from old metal, the Ace of Spades is made for the heavy digger. Some say it's overkill, but anyone who dreams of spending another perfect day ruling the world of diggery with an iron fist, this is the ideal purchase, lemme tell you.
List price: ₡3000.
Made from four Metal Bars, six Molybdenum Ingots and a Wood Post using a Tinkertool.
