The Shockleader Knot
The Shockleader Knot also known as the Shore Leader Knot is used to join a thinner casting line to a much thicker leader line. It makes a neat tapered knot that will cast smoothly through the rod guides without snagging. The use of a Shock Leader is essential to minimize break-offs while casting. Break-offs usually result in severe backlash and can be dangerous to bystanders. A rule of thumb is to use at least 10lb of Shock Leader for every 1oz of lead being cast. So if you are using a 6oz lead you should use at least a 60lb Shock Leader. For safety reasons and to avoid loss of tackle, we advise you to use a high quality Shock Leader such as Ultima Powerflex.
Tie the thick leader line around the thinner main line using one to three turns. Wet the knot and draw it firm but not too tight.
Take the free end of the main line and loop it back towards the first knot. Then wind it five times around the shockleader inside this loop moving away from the first knot. Wet and draw firm but not too tight.
Wet and draw the knot together by pulling on both the shockleader and the main line slowly to bring both parts together as a small neat tapered knot.
