          cordage.  Other synthetic ropes  are produced  as  braided  (or plaited) or as


          sheath-and-core  ropes.  Braided rope  can  be  constructed in  a variety of ways


          but  the  most common forms  are  made  up  of eight or sixteen  braids.  Some


          braided  cordage  is  hollow; this  makes  a very flexible  rope,  but it  does flatten


          out  during  use.  In most cases,  a separate  core  is  used  to give strength  and
                                                                          ' .
