In the video, a person is seen holding a knife in their hand. The person then proceeds to open the knife, revealing the blade. The person then closes the knife and opens it again, repeating this action several times. The knife appears to be of a standard size and has a black handle. The blade is silver and has a sharp edge. The person's hand is steady as they manipulate the knife, and there is no visible damage or defect on the knife. The background is not clearly visible, but it appears to be a dark surface.
