Overlap the two lines. Holding the straw and the lines together, wrap the lighter line (blue) around the straw and both lines. Make six complete turns, pass the line through the straw and tighten the knot neatly around the straw. Withdraw the straw. Lubricate, pull the knot tight, and trim the ends.
Description: The Nail Knot is an important fishing knot used to join two lines of different diameters and allows for line diameters to diminish down to the fly, i.e., it is useful for attaching your backing to the fly line, and your fly line to the leader, or tippet.
Name: The Nail Knot was originally named because a nail was inserted as a guide when threading the line. Today, it is easier to use a small straw – if you can find one.
Tying it: There are several ways of tying the Nail Knot. The animation shows the smaller line being threaded through the loops using a straw.
Alternative: Alternatively, the line can be threaded beside a nail (hence its name) or pulled through with a needle.
Advantages: The Nail Knot makes a smooth compact knot that readily passes through the guides.
