Identify Movie for my Column

Now, I thought you could help me find the title of a Kung-fu film I saw as a kid. I only remember one scenes, in which the protagonists enter a restaurant and are assailed by an assassin, who introduces himself and demonstrates his skills only to be struck down by another assassin, who introduces himself and demonstrates his skills only to be struck down by another assassin etc... This seemed to go on forever and the assassins and weapons used seemed to get even more bizarre as time went on. I definitely remember one of them used razor sharp chopsticks as their weapon of choice.

Not much to go on, I know...
