During the big highway scene, when Trinity and the keymaker are riding on a motorcycle, there are two trucks next to each other. Morpheus puts a sword in the left truck's side so he can stand on it and pull the keymaker off the moving motorcycle. Morpheus pulls the keymaker onto the other truck on the right. Then Morpheus jumps onto the same truck with the keymaker. Later, while Morpheus is fighting an Agent on the truck, you see the sword again.
