Thief Knot


Step 1
Cross the ends so they start on opposite sides.

Step 2
Tie what looks like a square knot.

Step 3
The tags will leave opposite each other.

Step 4
Dress it.

Step 5
Remember it spills if you pull the standing parts.
The drawing follows this tying order. Pause, step, or scrub to stay with the words. The standing line runs to the reel. The tag is the short end you trim. Skin-hook means the point lies flat in the plastic, not out where grass can grab it.
Common mistakes
- Tying a real reef knot and calling it a thief knot.
- Using it as a bend under load.
