In this video, a person is seen holding a knife in their hand. The knife has a black handle and a silver blade. The person then proceeds to open the knife by flipping the blade outwards. The blade is then closed by flipping it back into the handle. The person repeats this action several times, opening and closing the knife with ease. The background is a plain surface, and there are no other objects or people visible in the video. The focus is solely on the knife and the person's hand movements.
