Hi Ted --

   Thanks for those references.

   Perhaps they may sense in the original context of the message.  When I read "bend", I assumed the author was talking about
joining two ropes together, which these knots do NOT do.

   Nonetheless, it's an excellent knot to know.  I'll be substituting this for bowlines in the future.

   So much to learn...
