San Diego Jam Knot

This knot was popular only in the sport fishing capital of San Diego but later gained widespread recognition with anglers all over the world as an excellent knot. It attaches a line to a swivel, hook, artificial fly or clip. Also known as the reverse clinch or the Heiliger knot it can be tied with many types of fishing lines including fluorocarbon, monofilament and braided v/s the Palomar knot that is not as powerful with braid as it is with mono. It has won rave reviews with fishermen.

  1. Improved clinch knot – Like the San Diego jam, it slides close to the hook. However, it doesn’t perform as well with braid in which it is slippage-prone. Weaker. Wraps around a single line instead of double.
  2. Uni knot – As compared to the San Diego jam that wraps the tag end on the outside of the double line, it is wrapped on the inside of the loop that is created by doubling the line and bringing the tag end back towards the eye of the hook.
