Towards the end of the mvie when Casey jones Danny are saving splinter, the bald guy Tatsu, tries to stop them. Casey gets knocked down next to a bag of golf clubs. Casey picks up a "Wood", a type of club, then he hits Tatsu with the club. The scene cuts away to show Tatsu flying in the air, when it cuts back to Casey the club has changed to an "iron". An iron is a totally different style of club. It has a lot smaller head and is shaped differently.
