Arbor Knot.

The arbor knot is a quick, yet effective knot to attach your line to the center of the spool (the arbor). While it's not the strongest knot, it doesn't need to be because it's only job is to keep the line snug on the spool without free-spinning around it.

How to tie the Arbor Knot

  • Wrap your line around the arbor of the spool with the tag end of the line. 
  • Then tie a simple overhand knot around the standing part with the tag end.
  • Tie a second overhand knot in the tag end just an inch or two from the first overhand knot.
  • Pull the standing part of the line to slide the first overhand knot down to the spool and the second knot to jam against the first. 
  • Trim tag end close.


Surgeon's Knot. 

This knot ranks as one of the best and easiest to tie knots for joining lines of equal or unequal diameters. In low light conditions or with cold hands or when time is of the essence (during a hot bite and you need to get back in the water quickly

How to tie the Surgeon’s Knot:

  • Lay the line and leader on top of one another overlapping each other by several inches.
  • Form a simple loop
  • Pass both the tag end and the entire leader through the loop 2 times.
  • (Optional) Pass both tag end and leader through the loop an additional time to tie the 'Triple Surgeon's Knot'.
  • Moisten knot and pull all 4 ends tight.


Nail Knot.

This particular knot is popular with fly anglers because it has a smooth, streamlined profile that runs through the guides on a fly rod with little to no resistance.

How to tie the Nail Knot:

  • Place the fly line just beyond the end of the tube. Position the butt end of the leader on top of the fly line.
  • Wrap the leader around the fly line and tube five or six times (make sure to place the coils close together so that it is easier to close the knot).
  • Use your fingers to pinch the coils in place, and then insert the tag end of your leader into the tube and push through.
  • Gently remove the tube, wet the coils, and tighten firmly by pulling on both ends of the leader.
  • Trim the tag ends if needed.


Non-slip Loop Knot.

The Non-Slip Mono Loop is also known as the “Kreh Loop” as it has been popularized by fishing legend Lefty Kreh. As its name suggests it forms a non-slip loop at the end of a fishing line. 

How to tie the Non-Slip Loop Knot

  • Make an overhand knot in the line about 10 inches from the end. 
  • Pass the tag end through the hook eye and back through the loop of the overhand knot.
  • Wrap the tag end around the standing part 4 or 5 times. 
  • Bring tag end back through overhand knot, entering from same side it exited from before.
  • Moisten he knot then pull slowly on the tag end to cinch the wraps loosely together.
  • Then pull the loop and the standing line in opposite directions to seat the knot. 
  • Trim tag end.
