ABSTRACT:
A cutting appliance for cutting a thin film has a cutter with a cutting edge held in a frame which slides on the thin film. The cutter is positioned to extend down to the plane of the bottom of the frame, where said frame has an opening therein. A magnifying glass is positioned obliquely with respect to the thin film and has a focal point substantially at the cutting edge of the cutter to enable good viewing by the operator of the appliance.
