Fans of Avatar: The Last Airbender will doubtless recognise the symbolic mask of the Blue Spirit, which belonged to Ursa, the expatriated mother of Zuko, the master swordsman, who then used it as a disguise in a dire hour of need. Now, the mask has been reimagined as an awesome bottle opener, which also has a handy magnetic backing that allows for easy storage on your fridge - ideal for when you need to call upon the Blue Spirit!
