I'd love to sell you one, don't get me wrong, but if all you need is a profile (which is a 2d cutout as I understand the term) you might be overthinking this particular project. I'd suggest laying the tool in question down on a piece of paper, tracing around it with a magic marker, then photographing the result with a digital camera (make sure you are lined up straight in front of it to avoid distortion).
Bring that up as a background image in your CAD program, and retrace it with your vector curve tools. This will make a line that your CAM program can follow when routing out the shapes in engraving mode. Of course, if you don't have all that gear, you can achieve pretty much the same result by tracing directly onto the plywood board and following the line with a sabre-saw.
