In the video, a person is holding a knife and opening it. The knife has a black handle and a silver blade. The person opens the knife by pressing a button on the handle, which causes the blade to slide out smoothly. The blade is then held in place by a locking mechanism. The person then closes the knife by pressing the same button, causing the blade to slide back into the handle. The knife appears to be sharp and well-made, with a sleek design.
