Mastering the Rethreaded Figure 8: A Step-by-Step Guide for Climbers
Climbing demands respect. Respect for the rock, respect for the environment, and perhaps most importantly, respect for your safety. A crucial part of climbing safety is knowing how to tie reliable and strong knots. Among the most fundamental and trusted knots in climbing is the rethreaded figure-8 knot, also known as the Figure-8 Follow Through. This knot is used to attach the rope to your harness and is celebrated for its strength, ease of tying, and relatively easy visual inspection. It’s strong enough to withstand the forces generated during a fall and is relatively easy to untie even after being heavily weighted. This comprehensive guide will walk you through the process of tying a perfect rethreaded figure-8 knot, ensuring you can climb with confidence and security.
## Why the Rethreaded Figure 8?
Before diving into the steps, let’s understand why the rethreaded figure-8 is such a preferred choice for climbers:
* **Strength:** The figure-8 knot is inherently strong. Its design distributes the load evenly, minimizing the risk of weakening the rope.
* **Security:** When tied correctly, the rethreaded figure-8 creates a secure and reliable connection between the rope and your harness.
* **Ease of Inspection:** The knot’s clear and recognizable form makes it relatively easy to visually inspect for proper tying and potential issues.
* **Ease of Untying:** After being loaded in a climbing fall, some knots can be extremely difficult to untie. The figure-8 generally remains manageable to untie, even after a significant load.
* **Versatility:** While primarily used for attaching to a harness, variations of the figure-8 can be used in other climbing scenarios.
## Essential Terminology
Before we start tying, let’s clarify some common terms:
* **Working End:** The end of the rope you are actively using to tie the knot.
* **Standing End:** The inactive portion of the rope that is not being used to tie the knot.
* **Bight:** A loop formed by bending the rope back on itself, keeping the sides parallel.
* **Harness Tie-in Points:** The designated loops on your climbing harness designed for attaching the rope (usually the belay loop and leg loop tie-in points).
## Step-by-Step Guide to Tying the Rethreaded Figure 8
Now, let’s get down to the practical part. Follow these detailed steps to tie a perfect rethreaded figure-8 knot. Remember to practice this knot repeatedly until you can tie it quickly, accurately, and without hesitation.
**Step 1: Creating the Initial Figure 8 Loop**
1. **Hold the Rope:** Hold the rope in your hand, leaving a generous amount of working end – at least 1 meter (3 feet) is recommended. This provides enough rope for the knot and a sufficient tail. The length of the tail is very important, as you need enough to be able to easily inspect the knot later on.
2. **Form the Loop:** Create a simple loop in the rope by bringing the working end over the standing end. Think of it as forming the number “6”.
3. **Pass the End:** Bring the working end across the front of the loop you just made.
4. **Tuck and Tighten:** Now, pass the working end *under* the loop and then *through* the initial loop you created from the top. This completes the figure-8 shape.
5. **Tighten the Initial Knot:** Before threading it through your harness, tighten the initial figure-8 knot slightly to make it easier to handle. This is just a preliminary tightening; the final tightening comes later.
**Step 2: Threading Through the Harness**
1. **Thread Through Tie-in Points:** Take the working end of the rope and pass it through *both* of the harness tie-in points (the belay loop and leg loop tie-in points). It’s crucial to thread through both points for maximum security. Ensure the rope passes smoothly and doesn’t get twisted.
2. **Direction Matters:** It generally doesn’t matter if you thread the rope from the top or bottom of the loops, but it’s good to be consistent. In most situations, it is taught to thread from top to bottom.
**Step 3: Rethreading the Figure 8**
This is the most critical step. You’ll be retracing the original figure-8 knot with the working end, effectively “following through” the initial knot.
1. **Follow the Path:** Carefully guide the working end back through the figure-8 knot, meticulously following the exact path of the initial knot. This means retracing every twist and turn. Pay close attention to avoid crossing strands or creating any irregularities.
2. **Parallel Strands:** The goal is to have the working end run parallel to the standing end throughout the entire knot. This ensures even load distribution and maximum strength. If the strands cross or diverge significantly, the knot is not tied correctly.
3. **Patience is Key:** Take your time and double-check that you are following the correct path. Rushing this step can lead to errors that compromise the knot’s integrity.
**Step 4: Tightening and Dressing the Knot**
1. **Initial Tightening:** Before fully tightening the knot, take the slack out of both the working end and the standing end. Gently pull on each strand to remove any looseness.
2. **Systematic Tightening:** Now, begin to tighten the knot systematically. Start by pulling on the standing end to set the knot against the harness tie-in points. Then, pull firmly on the working end to tighten the knot itself.
3. **”Dressing” the Knot:** “Dressing” the knot means ensuring that all the strands are neatly aligned and parallel. There should be no twists, kinks, or crossed strands. A well-dressed knot is easier to inspect and is more likely to perform optimally under load. Use your hands to carefully adjust the strands until the knot looks clean and organized.
4. **Final Tightening:** Give the knot one final, firm tightening. This ensures that all the components are snug and secure.
**Step 5: Inspecting the Knot**
This is arguably the most important step of all. Never trust a knot without a thorough inspection. Develop a habit of carefully checking every figure-8 knot you tie, and encourage your climbing partners to do the same.
1. **Visual Inspection:** Carefully examine the knot from all angles. Look for the following:
* **Parallel Strands:** Verify that the working end runs parallel to the standing end throughout the entire knot.
* **No Crossed Strands:** Ensure that no strands cross over each other within the knot. Crossed strands can weaken the knot and make it more prone to failure.
* **Proper Form:** The knot should maintain its characteristic figure-8 shape. Any significant distortion or irregularity could indicate a problem.
* **Tightness:** The knot should be tight and compact. There should be no loose or floppy strands.
2. **Tail Length:** Check that the working end (the tail) extends at least 15-20 centimeters (6-8 inches) beyond the knot. This provides a safety margin and prevents the knot from unraveling under load. Some climbers use the “fist” rule: the tail should be at least as long as your fist is wide. If the tail is too short, retie the knot with more rope.
3. **Harness Connection:** Confirm that the knot is properly connected to both the belay loop and the leg loop tie-in points on your harness. Make sure the rope isn’t twisted or caught on anything.
4. **Ask for a Second Opinion:** If possible, have your climbing partner inspect your knot as well. A fresh pair of eyes can often spot errors that you might have missed.
## Common Mistakes to Avoid
Even experienced climbers can occasionally make mistakes when tying a rethreaded figure-8. Be aware of these common errors and take steps to avoid them:
* **Forgetting to Rethread:** This is the most critical mistake. Failing to rethread the working end through the initial figure-8 creates a severely weakened knot that is highly likely to fail under load. Always double-check that you have properly rethreaded the knot.
* **Incorrect Rethreading:** Even if you rethread the knot, it’s possible to do it incorrectly. Make sure you are following the exact path of the initial knot and that the strands are parallel. Avoid crossing strands or creating irregularities.
* **Short Tail:** A tail that is too short can allow the knot to unravel under load. Always leave a tail of at least 15-20 centimeters (6-8 inches).
* **Loose Knot:** A loosely tied knot is more likely to slip or come undone. Tighten the knot firmly and systematically, ensuring that all the components are snug.
* **Twisted Rope:** Twists in the rope can weaken the knot and make it more difficult to inspect. Ensure that the rope is running smoothly and that there are no twists near the knot.
* **Skipping the Inspection:** Never skip the inspection step. A thorough inspection is your last line of defense against potential errors.
## Practice Makes Perfect
The key to mastering the rethreaded figure-8 knot is practice. Practice tying it repeatedly until you can do it quickly, accurately, and without hesitation. Practice in various situations, such as in the dark or with gloves on, to prepare yourself for real-world climbing scenarios. You can practice at home, at the gym, or anywhere you have access to a rope and harness.
## Variations and Alternatives
While the rethreaded figure-8 is the most common choice for attaching to a harness, there are other knots that can be used in climbing:
* **Bowline:** The bowline is another popular knot, known for its strength and ease of untying. However, it is generally considered less secure than the figure-8, as it is more prone to loosening under load. It also requires more skill in tying and inspection.
* **Figure-8 on a Bight:** This variation of the figure-8 creates a loop in the end of the rope. It can be used for various purposes, such as creating an anchor point.
* **Double Figure-8 Loop:** This knot creates two loops and is often used for equalizing loads in anchor systems.
However, for the purpose of attaching the rope to the harness, the rethreaded figure 8 remains the gold standard due to its balance of strength, ease of use, and ease of inspection. Learning other knots is a valuable skill for climbers, but mastering the figure-8 should be a top priority.
