In the video, a person is holding a knife in their hand. The knife has a black handle with a textured surface and a silver blade. The person is using their thumb to push the blade out of the handle, revealing the sharp edge of the blade. The blade is then retracted back into the handle with a smooth motion. The person's hand is steady, and they seem to be demonstrating the knife's functionality. The background is blurred, but it appears to be a dark surface. The video is shot in close-up, focusing on the person's hand and the knife.
