The Two-Turn Clinch has been around since the turn of the century. It's stronger than the Improved Clinch and almost as easy to tie.
Pass the line through the eye of the hook, swivel, or lure two times to form a small double loop.
Finish the loop between your thumb and forefinger, and make five turns around the standing line. Insert the tag end through the double loop.
Hold the tag end and standing line while pulling up the coils. Make sure the coils are in a spiral, not overlapping each other. Slide against the eye.
Clip the tag end.
