This knot is used primarily by rock climbers to provide a life-line. Since this knot is used as a life-line, it is very important to be able to tie it correctly Your life could depend upon it! Don't worry, with this tutorial and about 5 minutes of practice, you can have this knot mastered!

Things you will need: - Climbing Harness - Climbing Rope If you are looking to learn this knot but dont have climbing gear, a belt loop and any rope will do.

Climb Safe With a "Figure 8 Knot"

Throughout this tutorial, I will be discussing different parts of the rope. To make these instructions as clear as possible, I will define a few terms that I will use throughout the tutorial. The " Anchor End " of the rope will generally be at the top of the images. This is the end that would be anchored to the wall or rock, and does not move. We will not be doing much with the "anchored end". The " Tail End " of the rope is the opposite end that we will be dealing with.

I will call this the "tail" for short. Now that we have some terms to work with, lets get started. This knot has several parts to it.

figure 8 knot

The first part of the knot is just tying a basic "figure 8". To tie the first "figure 8", there are four simple steps. As shown in the second picture 3 - Bring the tail down through the first loop. As shown in the third picture 4 - Finally, pull the two ends to make the knot a little bit tighter and easier to deal with. Shown in the fourth picture After these four steps, you should end up with a knot that resembles a "figure 8".

In order to secure the rope to the harness, simply thread the tail end of the rope through the front loop in the harness as shown in the picture below. This step is obviously very important. Hint: To be even more secure, feed the tail end of the rope through leg loop and waist loop rather than the front "tie in loop".

After looping the rope through the harness, you have to thread the tail end of the rope back through the knot, following the first "figure 8". I have divided this process into five smaller steps in order to make it more clear. Shown in the second picture 3 - You simply need to bring the tail back over the top of the knot to the left. Shown in the third picture 4 - Bring the tail end up through the far loop following the anchored end.

Figure Eight Knot

Shown in the fourth picture 5 - Finally, pull the knot tight. After completing the Figure 8 knot, you will want to secure the tail end of the rope out of the way. There are a couple different ways to do this, the way that I will demonstrate is using what's called a "Stopper Knot".

This secondary knot is pretty simple, but I have once again divided this process into several smaller steps.

As shown in the first picture 2 - Wrap the tail back underneath the two vertical segments. As shown in the second picture 3 - Simply repeat the first two steps, wrapping the tail around again. As shown in the third picture 4 - This step in the fourth picture may look complicated, but all you need to do is insert the tail up through the two loops that you have just made. Ideally, the tail would be a little shorter than what I have shown.

Tie a Figure Eight Knot

Now that you have mastered the Figure 8 knot, you can securely harness yourself into a climbing rope. Remember, there are many other skills that go into setting up an anchor and belaying a climber. This tutorial only covers the figure 8 knot. For more information, there are many great websites that demonstrate how to correctly set up a safe climbing system I've posted a few below.The figure eight knot, also known as the Flemish knot and savoy knot, is the unique prime knot of four crossings It has braid word.

It is a 2- embeddable knotand is amphichiral as well as invertible. It has Arf invariant 1.

It is not a slice knot Rolfsenp. Furthermore, Ferguson has carved the BBP-type formula for the hyperbolic volume of the knot complement discussed below on both figure eight knot complement sculptures commissioned by the Clay Mathematics Institute Borwein and Baileyp.

The hyperbolic volume of the knot complement of the figure eight knot is approximately given by. OEIS A Exact expressions are given by the infinite sums. Weisstein, Sep. Higher-order identities are. Another BBP-type formula is given by.

figure 8 knot

Everything is new: slipping into a harness, buckling down your helmet, shoving your feet into small climbing shoes, and tying into a rope. Some are even simpler and easier to learn than the figure eight. Here is a video that very clearly shows how a figure eight functions under weight. In this video, the knot is being pulled until it breaks. During this particular pull test, the knot failed at 6,lbs. But keep in mind that the overall strength of any knot depends on a lot of factors including the age and condition of the rope, how the knot is being weighted, etc.

While there are many knots out there to choose from such as the bowline family and the brotherhood knot, this one should be your go-to unless you have a good reason to suggest another knot! These other options will work just fine, but they are harder to check and there is little to no margin for error — they must be tied perfectly.

If you undo another pass through, then the knot would come undone under weight. Fully Tied One Gesture Two Gestures Here is a video that very clearly shows how a figure eight functions under weight.

However, in your personal time you should be aware that it is not necessary and actually makes the knot less safe. This is because it detracts from the number one reason why we use this knot — recognizability. The more we add to the knot, the harder it is to check those 5 sets of parallel lines. Share this Post:. Leave a Comment Cancel Comment.Unless you are boulderingyou'll need to tie the end of the rope to your harness before you climb.

The best way to do this is using a rethreaded figure of 8 knot. It's important that you do it correctly, as this knot connects you to the whole climbing system and keeps you safe. Try to avoid talking to someone or distracting them while they tie in. Accidents have happened because climbers were distracted halfway through tying in and then fell with a half-completed or incorrect knot.

Step 1 Make a loop about a meter from the end of the rope. Wrap the end of the rope around the base of the loop, then push the end through as shown. Step 2 You should end up with an '8'. Make sure the knot is around 90cm from the end of the rope. The exact length varies with ropes of different diameters. Step 3 Pass the end of the rope through both of the two points on the front centre of your harness — the same ones your belay loop runs through. It is important that the rope goes through your harness in exactly the same way as your belay loop does.

Step 4 Use the end of the rope to re-trace the figure Follow the twists of the rope starting from where it joins your harness. Step 5 Continue following the twists until you end up back at the start of the knot. Pull the whole thing tight. Step 6 Make sure the end of the rope is around 25cm long. If it is shorter, you'll have to untie and start again. After this, you will need to tie a stopper knot. Loop the short section of rope around the main length.

Step 8 Push the end of the rope through these two loops as shown. Step 9 Make sure the stopper knot is pushed right up against your figure-8 knot. Pull it tight. The purpose of the stopper knot is to ensure that you have left enough tail to stop the figure-8 failing — a short tail could slip through the knot.

Also, if you left a long tail dangling without a stopper knot, it could be mistaken for the main rope when clipping quickdraws, or the anchor.The following are steps that will instruct on how to tie a proper figure eight knot. The figure eight knot is designed to increase friction in the knot in order to severely reduce the amount of slippage in the knot. This is a basic, but essential knot that every aspiring climber should know.

Climbing should be done after receiving hands-on instruction from those who are experienced in climbing, and while being chaperoned by experienced climbers. Find an end of the climbing rope and make a small loop alien head in the rope. Ensure that the loop isn't too close to the end, maybe about a foot and a half from the end. Take the end of the rope and lay it on top of the loop.

Grab the end of the rope that is laid on top of the loop and wrap it around the bottom of the loop in order to make a loop around the original loop. Then take the end of the rope and poke it through the original "alien head" loop. Pull the end of the rope tightly until an 8 shape is made.

If the 8 shape isn't apparent, repeat the first three steps again. Most harnesses will have two dark loops on the front of the harness that you should loop the rope, starting with the bottom loop, through both. Pull the rope end all the way through in order to put the 8 near the harness. The rope that is poking out of the top of the harness should follow the section of rope that is coming out of the 8. Insert it in that part of the 8 and then follow that section of rope all the way around the outside of the 8 and then back inside the 8.

The rope will then wrap around the outside of the 8 until it is able to follow the last bit of the original 8 all the way outside of the knot. Is there is extra rope that you are worried about it getting in the way of your feet while you climb? You can tie a simple overhand knot in order to get the extra rope out of the way.

This is a simple loop around the long end and then you poke the short end through the loop that you just created. This will ensure your excess rope is out of your way.

It is used in climbing and caving where rope strains are light to moderate and for decorative purposes. The Flemish loop or figure-eight loop is perhaps stronger than the loop knot. Neither of these knots is used at sea, as they are hard to untie.

In hooking a tackle to any of the loops, if the loop is long enough it is better to arrange the rope as a cat's paw. The double figure eight is used to put a loop in the end of a rope, or around an object. It is relatively easy to tie and is secure, but can become difficult to untie after heavy loading, and can jam badly in any rope type. A figure-eight loop is created by doubling the rope into a bight, then tying the standard figure-eight knot.

In climbing, this knot is used to save time when repeatedly attaching the rope to climbing harnesses, using locking carabinerssuch as when a group of people are climbing on the same top-rope. Alternatively, to tie the knot directly around an object, the follow-through method must be used.

This is the standard method for attaching a rope to a climbing harness. Often an additional double overhand or half of grapevine knot or half of a double fisherman's knot "backup knot" is tied above the figure 8. The diameter of the loop should be kept small, to avoid being caught on protrusions while falling, or clipped into accidentally while lead climbing. From Wikipedia, the free encyclopedia.

The Ashley Book of Knotsp. Climbing: Knots. Tying a double overhand or barrel knot in front of the figure 8 follow through does not alter the failure mechanism of the knot. It simply adds another step to an already secure knot. When tied correctly, the knot is tight, with a 5- to 8-inch tail Tie the figure eight so that its loop is about the same diameter as your belay loop.

The figure eight knot does not require a backup knot. Climbing Magazine. Retrieved Eng, Ronald C. Mountaineers Books. For instance, the overhand knot can be used to secure rope ends after The rewoven figure eight is finished off by tying an overhand knot in the loose end of the rope. Wilderness Education Association U. Some people think stopping at this point is sufficient; others believe that since your life depends on this knot, you should back it up.

Stackpole Books. Courage Books. A stopper knot must be added when the threaded figure eight loop is used to tie on a line. American Alpine Institute.The Figure 8 is one of the most versatile knots for kayakers, rafters, canoeists, swiftwater rescue professionals, climbers and other outdoor folks to learn and use. It is also one of the strongest knots you can tie. It works for making a tie-down point along a length of rope and as a stopper knot at the end of one.

Climbers use it to securely tie into a climbing harness. You can also tie two different lengths of rope together with it. They tie you up to shore. To do just about anything with a rope requires putting knots in it. NRS Tiedown Straps do a lot of this for you, but many things demand the use of a rope!
