Written Instructions — Uni Knot

Thread through ring Pass 6 inches of line through the ring or eye. Double it back parallel to the main line.
Form a loop Fold the tag end back to form a loop alongside both the tag and main line strands.
Wrap 6 times Wrap the tag end around both strands and through the loop 6 times, winding away from the ring.
Wet and slide to ring Moisten thoroughly. Pull the main line to slide the coils toward the ring.
Seat and trim Seat the knot firmly against the ring. Trim the tag end to 1/8 inch.

Six wraps is standard for 10–20 lb line. Use 5 for heavier line, 7–8 for lighter line under 8 lb.
The uni knot on braided line requires extra wraps (8–10) because braid is slipperier than mono.
Two uni knots facing each other make an excellent line-to-line connection — the double uni.
Unlike many knots, the uni allows a small loop before seating — useful for lures that need action.
