Scroll Shears are used for cutting sheet metal or like sheet materials. They permit unlimited maneuverability in one direction, so that the operator may cut a square corner, a very small curve, or even cyclonical and involutes shapes. Shears or snips with an offset cutting edge with relation to the flank of the shear, in order to obtain clearance to scroll slightly to the right, while retaining full maneuverability to the left. An adjustable ride or hardened washer interposed between the cutting blades of the shears to facilitate adjustment of clearance after grinding.
