Poacher's Knot, also known as Double Overhand Noose, is a secure knot used for binding a rope to an object.
It is one the few knots suitable for tying even very slippery ropes made out of Dyneema and Spectra. For such ropes, there is even stronger alternative with an extra turn, known as Triple Overhand Noose. Common mistake when making this knot is making only one turn around the standing end, which leads to 'ordinary' Overhand Knot, which is not secure knot.
