The video shows a person holding a knife in their hand and demonstrating how to open it. The person's thumb is used to push down on a button on the handle of the knife, which causes the blade to slide out. The person then pulls the blade out further to show how it works. The knife appears to be a folding knife with a textured handle and a silver blade. The person's hand is visible in the frame, and they are wearing a pink fingernail polish. The background is blurred, but it seems to be a dark-colored surface.
