A game in which two competitors compete to see who has the largest knife. The one with the biggest blade wins. The rules state that at any given time a spoon can be produced after a knife is produced. If you can get the person who produced the spoon to admit that it's a spoon rather than a knife, you win.
It's a very popular pub sport in Australia, with debates even solved or resolved based on the outcome of knifey spoony.
