Zusammenfassung:The present invention relates to a tool for shaping and polishing an edge of an eyeglass lens. The tool includes a longitudinally extending body rotatable on the axis thereof, with a proximal portion and a distal portion. A first cutter extends axially and radially from the distal portion, and includes a first blade for shaping an edge of a lens. The distal portion has a first diameter defined by the first blade. A polishing hub is secured to and extends coaxially from the distal portion and is rotatable therewith. A second cutter is secured to and extends coaxially from the polishing hub and is rotatable therewith. The second cutter has a second blade for shaping the edge of the lens. The second blade defines a second diameter less than the first diameter. The present invention also relates to an edger having the disclosed tool, and a method of edging.
