This is the swiss army knife and dinosaur keychain that was used by Patricia Arquette to stab James Gandolfini in the foot in the Safari Inn scene. This is a larger version that would of been used in closeups and where Patricia held the knife with two hands. A standard swiss army knife would not have been large enough to achieve this. You can also see that the knife was welded "open" so that it wouldn't close on Patricia's hands while jamming it into Gandolfini's foot. There are still a few blood splatters on the dino's tail, foot and belly. A rare prop from a great film!
