The video shows a person holding a knife with a rainbow-colored blade. The knife is being held in the person's right hand, and the blade is being moved back and forth to show its flexibility. The blade appears to be made of a shiny, metallic material and has a smooth, curved shape. The handle of the knife is not visible in the video. The background is blurred, but it seems to be an indoor setting with some objects and possibly other people in the distance.
