History
The Double Overhand Stopper Knot is detailed in The Ashley Book of Knots (ABOK #516). Its simplicity and effectiveness have made it a staple for climbing, boating, and various utility purposes. Over time, it has become a foundational element in forming more complex knots, such as the Double Fisherman’s Knot and Poacher’s Knot.
Security Level
The Double Overhand Stopper Knot is one of the most secure stopper knots available. Its double-wrap design ensures it won’t slip, even under heavy loads. However, it can jam if subjected to extreme pressure, making it challenging to untie in such cases.
Downsides
- Prone to Jamming: Under extreme tension.
- Bulkier: Slightly bulkier than simpler stopper knots.
Structure
- Create a loop at the end of the rope.
- Pass the working end through the loop to form an Overhand Knot but do not tighten.
- Wrap the working end through the loop a second time.
- Tighten the knot by pulling both the working and standing ends until secure.
Pro Tip: Ensure a small tail extends beyond the knot for added security.
