Description:
The swinging "master stop" limits the cutting action to the cutting point for cutting curves; the majority of the edge will shear a straight edge.

The specifications note the tool's value for precise cutting of sheet metal templates, and "cornice work," and the drawings include a sample of the kind of cuts that can be obtained. Advertised as the "SEDLIN CIRCLE CUTTER."
