Constrictor Knot

Use: The Constrictor knot is one of the most effective binding knots. Simple and secure, it is a harsh knot which can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn. It is a very effective knot for constructing a pilot's ladder, as it will not slip when tied around wooden rungs.

How to tie:

Make a turn around the object and bring the working end back over the standing part.
Continue around behind the object.
Pass the working end over the standing part and then under the riding turn and standing part, forming an overhand knot under a riding turn.
Be sure the ends emerge between the two turns as shown. Pull firmly on the ends to tighten.

WARNING: The Constrictor knot's severe bite, which makes it so effective, can damage or disfigure items it is tied around.
