 Apr 21, 2013 Could someone demonstrate how the super 8 is no more redundant than the OP's figure 8? I've read arguments on both sides, but can't visualize it. Steve DavisFrom Tucson, AZJoined May 5, 200899 points

Get yourself a piece of cheap cord/string and tie a super eight in it, next cut one of the loops, then pull on the loop as if it were the master-point. You will notice that both loops fail. The BHK won't do this. Another knot that won't fail this way, uses less rope, and is easier to untie after loading than almost any other knot is the Bowline on a bight.

If any of those '4' strands fails, the whole thing goes. Dan AllardFrom West Chester, PAJoined Mar 28, 2011605 points

If any of those '4' strands fails, the whole thing goes. Can anyone show a documented case of a Super-8 or a bowline on a bight anchor failing because the "fold over" bight failed? I'm in serious doubt it ever has so I'd put this in the category of "technically possible but practically impossible". Allen CorneauFrom Houston, TXJoined May 6, 200891 points
