How To Tie Knots

Technically, a knot forms a loop or noose, fastens two ends of the same cord, or creates a "stopper" in the end of the rope. A bend joins two free ends together, and a hitch grips a shaft or another rope. Rope, cordage, or webbing is strongest when loaded in a strait line. When you bend the rope or web to create a knot, the strength of the rope is reduced. If you look at how rope is bent in a knot, you will see that stress is applied more on the outer part of the rope in the bend, while some compression may result in the inner part of the bend. This lessens the overall strands used in holding and may cause the outer strands to break sequentially.

If you only want to learn a few knots, I suggest learning the following: The overhand knot is something you should already know, learn the double overhand knot as well. As for loops, I suggest the bowline for boating and quick strength, the figure of eight for greater strength, and the alpine butterfly to tie off in the middle of rope for anchor points or to isolate bad areas and rubs. Joining two ropes (bends), learn the double fisherman's knot. As for hitches, learn the tautline hitch for camping, and the constrictor and italian hitch just for versatility.

In this order, try learning the double overhand, then the strangle-snare, then the tucked double overhand, then the bowstring, learning these knots together will reinforce each knot's method of tying. The strangle-snare is basically the double overhand with a loop instead of a stopper knot. The tucked touble overhand is the strangle-snare with a tucked end, and the bowstring could be called a tucked overhand loop (single loop), notice the end of the rope comes out on a different side of the loop.

Stopper Knots Loops Bends Hitches Miscellaneous Ascending Knots

Stopper Knots

Overhand Knot

\Probably the simplest knot in existence. Usually used as a stopper knot, but a double overhand is preferable.



Double Overhand Knot

     Better as a stopper knot than the Overhand, as it is less likely to pull through.



Loops

Overhand Loop

This is the simplest way to create a closed loop in the middle of a rope. Difficult to untie after loading.



Bowline

The bowline is easy to adjust and untie. Beware, though, that if tied incorrectly in can be unsafe. You should really tie a stopper knot in the loop with the loose end to prevent it from pulling through. During heavy loading, there is a rule of thumb which states that the loose end should be as long as 12 times the circumference for the sake of safety.



Yosemite Bowline

This is a variant of the basic bowline which gets around the problem of the knot loosening itself by taking the end of the rope and threading it back through the knot. This is a neat alternative to using a half-hitch to secure the end of the rope and the resulting knot has the strength of a figure of eight.



Figure-of-Eight

The Figure-of-Eight knot is probably the most useful of all climbing knots. It is easy to tie, easy to undo after a load has been applied, and puts the least stress on the rope when tied tight. It can be tied anywhere in the rope, but if it's near the end, it should be secured with a stopper knot to prevent the knot from un-doing itself.

There are generally two methods used to tie a figure of eight knot. The first method is used when a piece of equipment is clipped into the loop, the second when the knot is used to tie into something, for example, a climbing harness.



Figure-of-Eight Re-Threaded

The above re-threaded method is usually used to tie into a harness, and is just a case of making a figure-of-eight on the single rope, looping through the harness, and following the knot back through itself.



Figure-of-Nine

The figure-of-nine knot can be used as an alternative to the figure-of-eight. It is very similar to a figure-of-eight with just an extra turn before finishing the knot. It is a little bulkier than the figure-of-eight but has greater strength.



The Bowstring Knot

The Bowstring Knot is an ancient knot that is used as an eye for bowstrings. The knot is simple and strong. Once tied and pulled firmly, you do not want to untie it: you might call it a good 'tie-once' loop knot. The bowstring knot is appreciated because it is small, strong, secure, and easy to tie. It's neat because it does not have loose ends. If the loose (cross marked) end is not secured within the loop between the bow and loop, it is wise to add a small overhand knot as stopper.



The Strangle-Snare

The strangle-knot is an excellent knot to be used a running knot for a snare. The pull is easy adjustable. The more force is applied from inside the loop the more firmly the running knot prevents opening of the loop.



The Tucked Double Overhand

The tucked double overhand is very similar to the bowstring and the strangle snare knots. They are easy to learn together.

If you need a good looking and strong loop this is a good candidate. The Loose end must be at least two to three rope diameters long. But if you make the loose end inflexible with for instance glue, resch or by melting and you can hide it almost completely inside the two round turns. The "tucked double overhand" is a permanent loop. It jams badly, but that´s what it is made for.



Alpine Butterfly

A good knot for rebelays or for tying rub points out of a rope. Its main advantage is that the two strands of rope emerging from the knot are at 180 degrees to one another rather than emerging in the same direction as in a figure-of-eight for example. This makes it a good mid-rope knot and good for rebelays because it has greater strength than a figure-of-eight if the rebelay fails.



The Artillery Loop

A practical and easy to tie loop for applications needing a loop in another place than the rope-end but somewhere in the middle. It is not as strong as the butterfly but is a bit faster to tie and untie. As the name already suggests it was used by the artillery (for carrying their guns over the shoulder.) Do not pull the rope too hard when the loop is not loaded. It is best used as temporary knot for carrying things. As always, work up the knot neatly.



Bends

Fisherman's Knot

Probably the simplest knot for joining two ends of rope. Consists of two overhand knots.



Double Fisherman's Knot

Better than the Fisherman's Knot, this uses two double overhand knots. Good knot, as it can be difficult to untie. Check regularly for the loose ends getting shorter, and if so, re-tie. Tighten with body weight.



Sheet Bend

Occasionaly used to join the ends of ropes, may be adjusted easily, but can also come undone easily.



Hitches

Tautline Hitch

This knot is the standard for tying out tents in rough weather. This knot will slip up and down the rope by hand, but not by tention. You can also fix a draw-string sack with this knot.



Farmers hitch

This knot is excellent for tying in the middle of a climbing rope, for rebelays, for lashings of many kinds - anyplace a loop that leads fair both ways in wanted. The method for putting it in is simplicity itself:
  1. Take three turns of the rope round your hand, then:
  2. Move center part (b) over right part.
  3. Move new center part (c) over left part.
  4. Move new center part (a) over right part.
  5. Pull new center part (b) up to form the loop
  6. For most satisfying results, remove hand before fairing or loading knot.




Highwayman's Hitch

This knot can bear one's weight on one strand of the rope and can be untied by just pulling on the other strand. End 'B' is the load-bearing end. NOT RECOMMENDED for climbing, but excellent for robbing stagecoaches, when you want to get away quick with your rope.



Girth Hitch/Lark's Foot

Quick knot, but weak. Best avoided.



Constrictor Hitch

A new knot useful to cavers and climbers was invented early this century by Clarence Ashley himself. He calls it "the constrictor knot". It is enormously resistant to coming undone. Ashley claims it can be used in a pinch as a radiator hose-clamp.



Italian/Munter Hitch

An excellent self-reversing friction knot suitable for belaying people when climbing or using a ladder. It can also be used for abseiling and gives a smoother ride than a stitcht plate (IMHO).

This one is worth learning for all those occasions when you forget your Stitcht plate or descender.



Clove Hitch

The clove hitch is easily adjusted when place, but is not a particularly strong knot. If one side of the knot is to be loaded, place the diagonal underneath. If both sides are to be loaded, place the diagonal at the top. Tighten before loading, as it may run if loaded when loose.



Miscellaneous Knots

Bowline on the bight

This is another double loop knot suitable for rigging Y-belays. It has the advantage that is is a bit less bulky than the figure-of-eight on the bight.



Double Figure-of-Eight on the Bight

This double loop knot is most commonly used for rigging Y-belays. The nature of the knot means that it is reasonably easy to adjust the loops by moving rope from one of the loops to the other.



Ascending Knots

Prusik Loop




The French Prusik




The Kleimheist




The Hedden Knot, also known as Kreutzklem

First published in 1960 in Summit Magazine. In 1964, the name Kreutzklem was attached to it by someone in the German mountain troops who was shown it by an officer serving in the US Air Force. The Kreutzklem name (cross-clamp) was applied because the original inventor (Chet Hedden) got lost somewhere along the way when it was shown to different people in Europe.
