Abstract
A butterfly duster is disclosed having a novel folding duster head. The wings of the duster head are opened and closed with a fork actuator arrangement that interacts with a gliding surface and retention walls on each wing to allow each half of the fork actuator to glide along the surface of each wing in a controlled and linear manner without the need for different materials between the wings and each gliding surface. Linear guides and linear guide slots provide further control of the fork actuator as it rides along a slide coupling while opening or closing the wings of the duster head.
