Hi KnotMe
In Roger E. Miles ‘s book Symmetric Bend How to join Two Lengths of Cord, the ABOK#1424 is also called Triangular Bend. It composes a Grief Knot and a Half Knot. While Grief’s Great Bend (my new bend) also composed a Grief Knot and a Half Knot (twisted in the other way).
ABOK#781 can capsize to Ashley’s Bend.
