The cutter tips are carbide these days, and are fairly cheap (dunno about
CriCut specifically).

They'd handle soft copper easily although hitting the fibreglass underneath
would dull them.  Maybe you could combine this with the mythical EDM method;
use the EDM to burn away the unwanted (and isolated) bit between the tracks.
