I'm not at the hangar but I believe it was the ZBSC5 Sabre Cut.  The RotoZip
is pretty powerful and you will want to move too fast.  So cut slow.
Experiment on a piece that you know is going to get cut away.  Trying going
fast.  You will end up with a 'chipped' cut and will have to do a lot of
sanding to get all the stress cracks out.  Go slow and sand with 40 then 80
grit to get the edge nice and smooth.
