Churchkey Can Co.
Not too long ago, mental_floss had an article about bygone items that included a church key. Young commenters were mostly familiar with the item they know as a “bottle opener,” but didn’t know it was once called a “church key.” That term is back now, thanks to the Churchkey Can Company, which brews beer sold in flat-top cans that require a church key to open them. If that’s the major selling point, you have to wonder whether it will last past the novelty phase. That will depend on whether the beer is good! Link
