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]

• 
  1. Start with a rope end.
• 
  2. Start an overhand knot, leaving enough rope for the loop and the rest of the knot.
• 
  3. Complete the overhand knot.
• 
  4. Form the loop by wrapping the working end around, and then form a bight in the working end.
• 
  5. Feed the bight through the overhand knot.
• 
  6. Wrap the remaining working end around the back of the knot.
• 
  7. Feed the working end up through the bight.
• 
  8. Tighten. This is the completed loop.
