Back in the 80s there was a suitcase set. Can't recall the name but think it came from Japan initially.

The all in one club shown above has had several version. I used to carry on along with a putter that broke down. I found the all in one club's putter was not comfortable.

For me it allowed a quick round at the drop of the hat, but for me the distance was limited since there was no woods and back then my 1 iron shot wasn't all that great but playable.
