Fly Fishing Knots: Non-Slip Mono Loop Video

The Non-Slip Mono Loop is a very strong loop knot that allows a fly to hang free at the tippet connection. It's best in monofilament smaller than 20 lb test.

See detailed instructions below for each step in tying the Blood Knot.
  1. Start by making an overhand knot in the leader before doing anything with the fly. In this case, you should allow about 10 inches of tag end. Don't tighten the loop. Pass the tag end of the leader through the hook eye.
  2. Bring the tag end back through the overhand knot, making sure that it enters the loop formed by the overhand knot on the same side that it exited when you tied the overhand. The distance between the fly and the overhand knot determines the size of your loop, so work the knot up or down the standing part of the leader until you get the distance you want.
  3. Wrap the tag end around the standing part of the leader, just as you would in tying a clinch knot. Make 6 turns for material less than 8-lb test, 5 turns for material up to 40 lb.
  4. Pass the tag end back through the original overhand knot one final time. Again, it must enter the loop on the same side that you have been using.
  5. Tighten the knot by first pulling on the tag end until the turns tighten against the overhand. Next pull tightly on the fly and the standing part of the leader to finish the knot. Trim the tag end.
