Have you tried using scissors to cut corrugated cardboard? Especially trying to cut curves? The difficulty seems self-evident.

For straight lines you need something like a box cutter -- with scissors it will neither be easy nor particularly straight. While for even medium-sized curves or smaller details you really do need something like this.

It’s possible but tricky. For grownups. Kids will bork the scissors or get a cramp.
