The composite knot is a form of jam knot that's designed to join two monofilament lines of greatly varying diameter—such as ten-pound test to 100-pound test. Most widely used to connect shock tippets in fly- and light-tackle fishing, the composite knot is tough enough to boat everything from billfish to giant tarpon. The knot can be tied quickly when larger fish move into an area unexpectedly or bottomfish break light lines in jagged rocks or wrecks.

Tie a loose overhand knot in one end of the heavier mono and feed the tag end of the light mono through the loop of the knot.

Step 3
Feed the tag end of the light mono under the first wrap at the overhand knot. Cinch the overhand knot in the heavy mono tight first, then pull both the standing and tag end of the light mono to snug the wraps. Pull the standing lines in opposite directions to lock the knot and trim both tag ends.
