Morning gents. Yesterday in my travels I stopped at a friend’s place, to give him a hand. After we finished he asked if I would like a beer. He got two beers and was looking around and said “where did I put the church key. ? How did a bottle opener become known as a church key?

I asked my Dad about this years ago, and I just did some quick searching.

Turns out he was right! According to The Old Farmer's Almanac:

What is the origin of the phrase church key when referring to a bottle opener?

Answer:

Apparently bottles, especially beer bottles, were once opened with heavy, cast iron openers that resembled the same type of key used to open church doors in Europe. The name stuck even for today’s modern openers.
