Knot Tying Guide: 8 Essential Knots and How to Tie Them
A friend once asked legendary survival instructor Larry Dean Olsen what one skill he would teach someone going into the wilderness for the first time. He did not say fire starting, water purification, or shelter building. He said knot tying. “Rope is the most versatile tool you carry,” Olsen explained. “But rope without a knot is just a string.”
Knots hold up your shelter, secure your gear, lower your loads, and can even save your life in a rescue scenario. According to the US Army Survival Manual FM 21-76, “Soldiers who cannot tie knots carry extra weight — they must improvise lashings, use excessive cordage, or watch their equipment fail at critical moments.” The same applies to hikers, climbers, campers, and anyone who ventures outdoors.
You do not need to know fifty knots. You need eight, practiced to the point of muscle memory.
The Bowline: The King of Knots
The bowline (pronounced “bo-lin”) creates a fixed loop at the end of a rope that will not slip or bind. Rescue professionals call it the king of knots because it can be tied one-handed — critical if you need to pull someone from a crevasse or rapid.
How to tie it: Form a small loop in the standing end. Pass the working end up through the loop, around behind the standing end, and back down through the loop. The phrase “the rabbit comes out of the hole, goes around the tree, and back down the hole” has taught this knot to generations of scouts.
The bowline retains about sixty percent of the rope’s breaking strength when properly tied, according to the International Technical Rescue Association. It excels at securing a line to a fixed anchor, creating a loop for hauling, or making a rescue sling. The only downside: it can shake loose under cyclic loading. Back it up with a stopper knot for critical applications.
The Square Knot (Reef Knot): Simple Joining
The square knot joins two ropes of equal diameter. It is the knot most people think they know — and the one most people tie incorrectly. A mis-tied square knot becomes a granny knot, which slips under load.
How to tie it: Take one end in each hand. Cross right over left and tuck. Then cross left over right (not right over left again) and tuck. The finished knot should lie flat and symmetrical, with each end exiting on the same side as its standing part.
The Boy Scouts of America Handbook warns: “Never trust a square knot for critical loads or life-support applications.” It is perfect for tying bandages, bundling firewood, or closing a stuff sack. It fails under dynamic loads and should never replace a figure-eight or bowline for climbing or rescue.
The Clove Hitch: Quick-On-Quick-Off Anchor
The clove hitch is the fastest way to secure a rope to a post, tree, or rail. It grips under tension and releases instantly when the load is removed, making it invaluable for shelter building and temporary anchors.
How to tie it around a post: Pass the rope around the post. Cross over itself and go around again. Tuck the working end under the last wrap. You can also tie it in the hand by forming two loops (one forward, one backward), layering them, and dropping the combination over the post.
Clove hitch performance depends on friction. On smooth surfaces like a metal pole, it can slip and should be backed up with a half hitch. On rough bark or timber, it holds reliably. Survivalist Dave Canterbury recommends the clove hitch for ridgeline anchors in tarp shelters because it is easy to adjust tension by sliding the hitch along the post.
The Taut-Line Hitch: Adjustable Tension
The taut-line hitch slides up and down a standing line but holds position under tension. This makes it the best knot for tent guy lines, tarp ridgelines, and any application where you need to adjust tension repeatedly.
How to tie it: Wrap the working end around the standing line twice above the point of attachment, then once below, and pass the working end through the loop created by the last wrap. The friction of the wraps against the standing line allows the knot to slide when manually pushed but grip when the line is under tension.
The taut-line hitch is one of the few knots that combines adjustability with security. A properly tied version on a 3mm paracord guy line can withstand winds of forty miles per hour before slipping. For heavier loads or wet conditions, add an extra wrap (making a three-wrap taut-line) for additional friction.
The Figure-Eight Follow-Through: Climbing’s Gold Standard
The figure-eight follow-through knot is the primary knot used in rock climbing and technical rescue. It creates a fixed loop that is strong, easy to inspect, and unlikely to shake loose.
How to tie it: Form a loose figure-eight in the rope about three feet from the end. Pass the working end through your harness tie-in points or around an anchor. Then thread the working end backward through the figure-eight, following the exact path of the original knot. Pull tight. The finished knot should have all strands parallel, with at least six inches of tail.
The figure-eight retains approximately seventy-five percent of the rope’s breaking strength — among the highest of any knot. The UIAA (International Climbing and Mountaineering Federation) recommends it as the standard tie-in knot for climbing because it remains stable even after prolonged loading and is easy for a partner to visually verify.
The Sheet Bend: Joining Ropes of Different Sizes
The sheet bend joins two ropes of different diameters or materials. Unlike the square knot, which requires equal-diameter ropes, the sheet bend grips effectively on slick cordage like fishing line, paracord, or wet rope.
How to tie it: Form a bight (U-shaped bend) in the thicker rope. Pass the thinner rope up through the bight, wrap around behind the entire bight, and tuck it under itself. For extra security on very different materials, add a second wrap to create a double sheet bend.
Nautical history records the sheet bend as one of the oldest knots still in active use, dating back to the age of sail. Its name comes from “sheet” — the rope that controls a sail’s angle to the wind. Modern applications include extending a ridgeline with different cordage, repairing broken lines, and creating loops for gear hanging in camp.
The Prusik Knot: Ascending a Rope
The Prusik knot is a friction hitch that grips a standing rope when weighted but slides freely when unweighted. It is the foundation of emergency rope ascent and self-rescue.
How to tie it: Form a loop of thin cord (typically 5-7mm accessory cord). Wrap the loop around the main rope three times inside itself. The resulting knot should slide easily when pushed and lock tight when pulled from below. A longer cord creates a foot loop; a shorter one creates a chest harness connection.
NOLS (National Outdoor Leadership School) teaches the Prusik as part of their standard mountaineering curriculum. According to their field manual, a properly tied Prusik on a 9mm main rope will hold over a thousand pounds of force without slipping. Always test your Prusik on the specific rope you are using — different diameters and rope textures affect grip.
The Trucker’s Hitch: Mechanical Advantage for Tension
The trucker’s hitch is not a single knot but a system that uses a loop and a half hitch to create a two-to-one mechanical advantage. It allows one person to tension a line far tighter than would otherwise be possible.
How to tie it: Tie a loop (such as a figure-eight on a bight) in the middle of your rope. Pass the working end around your anchor and back through the loop. Pull down to tension. The loop acts as a pulley, doubling your pulling force. Secure with two half hitches around the taut standing line.
This knot is essential for securing gear on vehicle racks, cinching heavy loads, and creating tight ridgelines for group shelters. Professional riggers and truck drivers have used variations of this knot for over a century because it reliably tensions lines to near-breaking capacity.
Knot-Tying Tips for Beginners and Common Mistakes
The most common mistake in knot tying is failing to dress the knot — pulling it into its final shape before applying load. A knot that looks right will slip or fail if the strands are crossed, twisted, or not seated properly. Always tighten by pulling each strand individually, working the knot into tight, symmetrical form.
Practice each knot until you can tie it blindfolded or behind your back. Survival situations often occur in the dark, in the cold, or with injured hands. If you cannot tie your knots by feel, you will not be able to tie them when it matters.
Use the right rope for the job. Paracord (550 cord) is excellent for general camp tasks but stretches under load and is unsuitable for climbing. Static ropes are for hauling and rappelling. Dynamic ropes absorb impact and are essential for climbing. Know which rope you are using and what it can handle.

Frequently Asked Questions
What is the most useful knot for survival? The bowline is the most versatile survival knot. It creates a reliable loop that does not slip, works with most rope types, and can be tied one-handed. It is useful for rescue, shelter building, gear hanging, and countless other tasks. Pair it with the taut-line hitch for adjustable tension on shelters.
What knot should I use to join two ropes? Use a square knot for ropes of equal diameter in low-load situations. Use a sheet bend for ropes of different sizes or materials. For climbing or load-bearing applications, never join two ropes with a knot — use a dedicated connector or prusik system instead.
How do I keep knots from slipping? Ensure the knot is properly dressed (all strands parallel, tight, and correctly seated). Add a stopper knot (simple overhand near the working end) as backup. For slippery synthetic ropes, choose knots with more friction wraps like the double fisherman’s or triple taut-line.
Does paracord work for all knots? Paracord (type 550) works well for most camp and survival knots, but its nylon construction stretches when wet and has a smooth surface that reduces friction in some knots. The taut-line hitch and clove hitch hold well on paracord. The bowline requires extra care to tighten fully.
What is the strongest knot? The figure-eight follow-through is the strongest and most reliable knot for life-safety applications, retaining approximately seventy-five percent of the rope’s breaking strength. For general utility, the double fisherman’s knot is among the strongest bends. No knot retains full rope strength — the rope itself weakens wherever it bends.
