Best cutting tool (large sheets with curves)

Just for yucks the other day I tried my Styrofoam cutter (heated wire) and it worked. I bit slow but it was only a 10W cutter. Assuming I what I have is not PVC and I can safely melt it, I was thinking about perhaps making a hotter wire under tension to cut the stuff.

Another idea was to make templates from wood and use a router with a small straight double fluted bit at high speed... Same as a CNC but by hand.

Not sure which would work better.. but something to play with over the spring time

Most coro is, but not all. There are PVC variations on it.. You can normally tell the difference, PVC stuff is heavier and more brittle.
 
When I done my candy canes I created a template out of chipboard first, then I was able to just staple the coro to it and get a decent cut with just a basic stanley knife
 
Hot knife or foam cutter plenty of shapes and different tips are available also referred to as a hot wire cutting tool
