Abstract: A tool for scaling fish includes a handle with a shaft rotatably mounted to the handle and projecting therefrom. A generally cylindrical scaling head is engaged on the shaft and rotated at a high speed. The scaling head has a circular array of relatively wide ribs spaced around its periphery and extending the length of the head. Each rib has a substantially flat top wall and flat angled sidewalls so as to form relatively sharp parallel wedge-shaped corners at the tops of the ribs. When the tool head is brought into contact with a fish, the moving ribs strip away the fish scales efficiently and effectively without damaging the underlying flesh of the fish.
