I've been waiting a couple of weeks for someone to say something about this,
but I've heard nothing yet, so I'm speaking my 2 centavos worth.  It could
well be possible for the "point of intersection" of the blades to move fas-
ter than light, but sure as heck one couldn't cause any motion to occur in
the far end of the scissors any sooner after BEGINNING to squeeze the han-
dles than it would take light to go from the handles to the far end of the
scissors.  Any attempt to do so would result in the relativistic effective
mass of the blades tending to infinity, so that no finite force could pos-
sibly move the blades that fast.

here's hacking,
