How to Tie the Strangle Knot

 

Usage

The Strangle Knot is a very strong binding knot, ideal for securing cylindrical objects like poles, rolls, or sacks. It provides a firm grip but is slightly less secure than the Constrictor Knot. Once tightened, it holds well under tension but can be difficult to untie, making it best suited for temporary but strong bindings.

Why Learn the Strangle Knot?

If you need a simple yet effective binding knot, the Strangle Knot is a great choice. It is easier to tie than some alternatives while still providing substantial security. This knot is especially useful for quick bindings and temporary lashings, making it a valuable skill for various applications such as camping, survival, and general utility work.

Common Uses

• Camping and Bushcraft: Tying sacks and securing gear.
• General Utility: Binding cylindrical objects like poles and rolls.
• Sailing and Boating: Attaching ropes to spars and masts.
• Medical and First Aid: Temporary tourniquets for emergency situations.

History

The Strangle Knot has been documented in The Ashley Book of Knots (ABOK #1239) as a close relative of the Constrictor Knot. Its structure is similar to the Double Overhand Knot but arranged to function as a secure binding knot. Historically, it has been used in various fields, from maritime applications to first aid, due to its ability to create a strong, non-slip hold on cylindrical objects.

Security Level

The Strangle Knot provides strong security when tied correctly but is slightly less reliable than the Constrictor Knot. It holds well under load but may require cutting if heavily tightened.

Downsides

• Difficult to Untie: Once tightened under load, the knot can be nearly impossible to release without cutting.
• Less Secure Than Constrictor Knot: While effective, it is not as tight or secure as the Constrictor Knot.

Structure

1. Wrap the rope around the object, crossing over the running line in the front.
2. Wrap the rope around a second time, following the same path.
3. Tuck the working end under both turns and pull tight.
