precision cutting the Craftsman Handi cut
  it looks like a garden shears but it has a sharp precision blade on one
jaw and a flat surface on the other. I have used it for cutting damper felt
in the field. I first used it for cutting and trimming a whole set of
dampers for a grand I was doing in a joint venture with another tech. I had
left my felt guillotine at my shop because I was sure he had one, he didn't
and I would have lost  several hours going back to get mine. I had my
handicut with me, we tried it and it worked very well.
Both the cutter and flat jaw are replacable as they wear or dull as the case
may be. As I say I don't know if this would work for your application but
it's something to consider.
