In the video, a person is seen holding a knife and demonstrating how to open it. The person uses their thumb to push down on a button on the side of the knife, which causes the blade to slide out. The person then uses their other hand to pull the blade out further. The knife appears to be made of metal and has a silver color. The person's hands are visible in the video, but their face is not shown. The background is blurred, but it appears to be a dark surface.
