The Perfection loop, also known as the anglers loop, is ideal for all types of fishing line especially thick line. It is used by fly fisherman to make a loop in the end of a leader or Tippet. In coarse fishing it can be used as an alternative to the figure of eight loop knot.
Perfection loop How to tie
Take a good length of line, create a loop crossing in front of the mainline.
Take the tail end and create a second loop around behind the first.
Pass the tail end between the two loops.
Hold the tail end and pull the second loop through the first and begin to tighten the knot. Pull on the tail end before fully tightening to adjust the size of the loop.
Moisten the knot with water or saliva, pull hard to fully tighten.
Cut off tail end to finish the knot.
