The water knot (also tape knot, ring bend, grass knot, or overhand follow-through) is a knot frequently used in climbing for joining two ends of webbing together, for instance when making a sling. Ends should be left long, knot should be tightened and inspected before each use. Difficult to untie.

What is the purpose of a water knot?
The water knot is a simple knot used to tie two ends of webbing together. Commonly, climbers use water knots to tie a single piece of webbing into a small loop for use as a sling. These slings are often used to ascend ropes or to capture the progress of a load when tied into a friction hitch.
How strong is water knot?
Tests show the water knot to reduce webbing strength around 30% (the CMC Rescue Field Guide App gives the water knot a 64% efficiency rating). This reduction in strength is a result of the bends in the knot and associated stress-concentration points.
What type of knot is the strongest?
The Palomar Knot is arguably the strongest all-around knot. Due to its use of a double line, it is as efficient at maintaining a high breaking strength as it is easy to tie.
Do knots weaken webbing?
Because tying a knot in webbing weakens the webbing, it should be avoided when not necessary.
What is a safety knot?
The overhand safety knot is used to create a secure end to a line that will stop fraying or any other potential damage. The process is simple. You make a loop at the end of the rope, pull the end through and then tighten it. You might look at this and say, “but that’s how I always tie a knot at the end of something”.
How strong is a tape knot?
Tape Knot » Bends
(Strength: 2/Security: 3/Stability: 2/Difficulty: 2) See below for what these ratings mean. The Tape Knot is a quick and simple knot which only slightly differs from the traditional overhand knot.
Which knot is used to prevent the end of a rope from slipping through the primary knot?
Stopper knot
| Stopper knot | |
|---|---|
| Typical use | Keeps the line from slipping out of things. |
What is the weakest knot?
The clove hitch is the weakest of the common climbing knots, at 60 to 65 percent.
Which knot tightens as you pull?
Uses: The Arbor Knot is used to attach the fishing line to the “Arbor” or “Spool Center”. In fact the Arbor Knot is really based on a noose knot and, therefore, pulling tightens it.
What is the tightest knot?
The knot, which researchers described earlier this year in Science , has now set a Guinness World Record. The 192-atom loop crosses eight times and is the most complex woven molecule ever made, Chemistry World reports.
Why do they call it a blood knot?
“Blood knot” may refer to, “a double overhand knot tied in a cat-o’-nine-tails.” A cat-o’ -nine-tails was a whip used for flogging in seafaring. I imagine it’s called a blood knot because it would cause lacerations and draw blood.
What is the best knot for fishing?
One of the most popular knots, the Palomar Knot is strong and relatively easy to tie. The Palomar knot is best for use with braided fishing line.
Which type of knot works best with webbing?
WATER KNOT
The most used, and most useful, knot in webbing is the WATER KNOT or OVERHAND BEND, which is tied by ‘re-threading’. This is used to join (bend) two ends of webbing together, often two ends of the same piece to make a loop or sling.
How much does a knot weaken a sling?
In addition, knotting slings reduces the strength of the sling by up to 50%, depending on the material, the knot being used and how it is tied (see How to Break Nylon and Dyneema Slings). It is worth bearing in mind that Dyneema® webbing used in climbing slings is actually a blend of nylon and Dyneema® fibres.
Which knot is used to rescue a person from a rooftop or a tree?
| Reef knot | |
|---|---|
| Caveat | Not secure as a bend unless secured by additional knots(ex: overhand). Spills easily if one of the free ends is pulled outward. Does not hold well if the two lines are not the same thickness. |
