This 'scrolling' jigsaw cuts perpendicular to the surface even on curved cuts. Lesser jigsaws start off perpendicular but as the cut progresses the blade bends to produce a non perpendicular cut. It cuts metals with the correct blade installed. The 'T' square shown attaches to the saw to make a cut a certain distance from an edge.

The scrolling knob on top allows you to change the direction of the cut without changing the orientation of the saw. It's possible to cut a complete circle with the saw always pointing in one direction by just using the knob on top to change the blade direction as needed. This is a unique feature of this saw.
