The Wolverine Original Vari-Grind Jig will properly shape and maintain the edge on standard bowl gouge, the modern side grind shape and the traditional fingernail shape. These shapes however are difficult both to grind and maintain. OneWay has spent a considerable amount of time and effort to develop a system which will consistently produce sharp, repeatable geometries on turning tools for the woodturner. This single attachment will produce every shape from the first mentioned fingernail grind right up to the side grind and everything in between to suit your needs.
