Near the end of the movie Die Hard: With a Vengeance (at around 1:44), where John and Zeus are handcuffed to the bomb in the ship, John talks about picking the lock. Suddenly he has a piece of a wire/cable in his mouth. What happened? Where did he get it from?
The wire came from the cable they used to get on the boat. The cable was a braided wire cable and a splinter from it ended up in his shoulder as they reached the boat.
