Clearly, you didn't understand it (and I suspect that whoever wrote it
didn't fully, either, or at least wasn't able to explain to
themselves). The 'length' of such scissors would have to be
infinitesimal. By that stage, other problems will appear.

They have expressed the standard SR description. Check any reasonable
physics text that deals with the superluminal scissors paradox. The
words in the FAQ are the result of stepwise refinement by several
authors from an original draft. Everyone is out of step but you... I
think that it could be clearer (it spends too much time describing
configurations that would not work and not enough time explaining the
one that does and why there is no conflict with SR). Also I reckon the
French guillotine with a gently sloping blade is a much simpler
geometry to analyse.

Mark it is you who does not understand special relativity. There is no
conflict at all with SR in the superluminal scissors "paradox". Nothing
physical is moving faster than the speed of light. You might be able to
grasp this if you imagine what observers on a pair of exactly parallel
blades would observe when they crossed.

As I pointed out the
technical issues with pivotted scissors can be neatly circumvented by
using a drop blade guillotine.

Nope. You can't get round SR.

There is no need to get around SR. It is your misunderstanding of SR
that is the problem here.
