In the video, a person is seen holding a folding knife in their hands. The knife has a black handle and a silver blade. The person's thumb is on the blade, and they are using their index finger to push down on a button located on the handle. As they press the button, the blade of the knife begins to unfold. The person continues to push the button, and the blade fully extends. They then release the button, and the blade retracts back into the handle. The person repeats this action several times, demonstrating the functionality of the knife.
