Here’s the Thor Movie Metal Mjolnir Hammer Keychain: a replica of the bane of frost giants and doom of the enemies of the shining realm of Asgard;  the weapon of Thor the Mighty Avenger. The nicely detailed hammer is 3.25 inches long and 1.5 inches wide in solid pewter and features the engraved legend “Whosoever holds this hammer, if he be worthy, shall possess the power of…THOR.”  So why not try to pick this up?  You never know…even if you don’t get godlike power you won’t lose your keys.  This is, after all, one big keychain!
