In the video, a person is holding a knife in their hand. The knife has a black handle and a silver blade. The person is using their thumb to push the blade out of the handle. The blade is sharp and appears to be made of stainless steel. The person then pushes the blade back into the handle, demonstrating how the knife can be closed. The person's hand is steady, and they seem to be experienced with using the knife. The background is a plain white surface, which contrasts with the black handle of the knife, making it easy to see the action.
