  Take a pair of scissors that span between the Earth and the Moon.  It 
has straight cutting edges open at the moon and just beginning to shear 
at the Earth end.

  As the scissors close, the shear point travels up the pair faster than 
light as the angle closes the Moon ends together.  Of course, the 
depends on how fast the blades close.  But the point of shear moves 
really fast.

  Shear press for sheet metal works on this principle.  The entire sheet 
gets cut in a single blade drop action, but the shear point is mobile 
allowing the event to occur with less shock and less force.  For thick 
steel, the shear angle is not needed, but a cherry hot ingot may be.
