The plot thickens.  What on earth are "hair-proof scissors"?  Scissors 
whose functioning cannot be impeded by hair?  Is hair-vulnerability a 
major scissors design flaw that has somehow escaped my notice all 
these years?

The green-and-blue plastic ones are the horrors I had in mind, BTW.  
It is a well-known fact that no one has ever, to this day, 
successfully cut a piece of paper with those so-called scissors.

who would like to know the singular for scissors.  One scissor?  One 
sciz?
