48. Steel Teeth
Appeared In: The Spy Who Loved Me, 1977
Used By: Jaws
OK, so a set of metal teeth is not really a gadget. But they're too badass to keep off the list. With these choppers, Jaws was able to bite through thick metal cables. Imagine if he got a hold of a person. The Broccoli family thought them cool enough to include them in the next film, Moonraker.
