The Tech Axe is a replacement to the standard Pickaxe, it has no special abilities, other than granting Contributor status, it is the rarest and hardest to get of the axes and is used as a prestige item to show off. Originally used as a reward, the Tech Axe was given to contributors of FortressCraft until the the end of June of 2011.
Post June 2011, it has only ever been given out for very special reasons and a players gamertag must be hard coded into the game by DjArcas to unlock it.
This axe has been discontinued, and is no longer awarded, except in very special circumstances. Instead, the Neoteric Axe is given out for being a loyal community member, and the Wiki Axe is given out for heavy Wiki contribution.
