Typical use	Forming fixed loop in end of a line

The trident loop is a fixed loop knot which can jam when heavily loaded. It was proposed as a replacement for the figure-of-eight loop for use in climbing by Robert M. Wolfe, MD, who developed it as a loop form of Ashley's bend. While some tests indicate its strength lies somewhere between the weaker Bowline and stronger figure-of-eight loop, the trident loop shows exceptional resistance to slipping in shock-loading tests.^[1]
