   I just use a sharp utility knife. If I'm worried about it, I'll put a straight edge up against the fin to keep the cut perfectly straight.

   I used a cutter designed for cutting plexiglass.  Cheap little tool picked up at a discount place, I think.  plastic putty-knife -like handle, curved hook blade. 

   When you draw it down the plastic along the edge of the jamb, it scrapes out a thin thread of plastic as it cuts.  4 or 5 quick passes and you're through.

   For plexi, you make a few passes then snap it at the line.
