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.
In January 2005, Martee was one of the first to post on Lynn Blake Golf. He was the subject of the user-funded Martee Makeover Challenge conducted over three days in The Swamp. Special videos were made of that experience for the sponsors. Martee also was a great help to me getting photos posted in a day when virtually no one on the golf websites was doing this.
