Here is a link to the history of the Church Key
with pictures. William Painter invented it two years after he invented the bottle cap. Must have been a frustrating couple of years.
After such a glorious start to his career Painter went on to patent an ejector seat for passenger trains.
Aside from the bottle and can opener all built into the same end, one of ours also has prongs that hook onto the edge of a jar lid to lift it and break the vacuum seal. Can't find a photo online.
It is so simple and effective. I really wonder about all those silly jar tools that try to grip the edges of the lid to apply extra twist.
The thing is a family heirloom from the 1960s or earlier. It originally had a colourful painted wooden handle but all the paint has long gone.
