The Reef Knot
One of the simplest of knots. Once uncommon in climbing circles, it has gained favour in recent years for tying abseil ropes together, though this use has declined since the uptake of the overhand knot.
|Ease of Tying||Possibly the simplest of knots.|
|Recognisable||Easy to recognise - the knot is symmetrical if tied correctly.|
|Also known as||Square knot.|
|Usage||Tying two ropes together.|
Easy to undo after loading.
|Disadvantages||Tying two ropes of different diameters.
Can work loose - best backed up with a double fishermans's knot, which sort of defeats one of the objectives of using such a simple knot.
Symmetrical: so has an increased tendency to catch when being pulled after an abseil.
