The Knot Tying Honor is a component of the Wilderness Master Award . |
1. Define the following terms
editIt's a good idea to begin this honor with the definitions so your Pathfinders have a working vocabulary of the various terms involved. Telling them to "make a bight" or "take the standing part" makes little sense until these terms are understood.
- a. Bight
- The term bight refers to any curved section, slack part, or loop between the two ends of a rope.
- b. Running end
- Also called the working end, it is the free end of the rope. This is the end of the rope in which a knot is being tied.
- c. Standing part
- The part of the rope between the Running end and the Standing end (the end that doesn't move, think of it as if someone is holding it)
- d. Underhand loop
- A loop formed by passing the running end of a line under the standing part.
- e. Overhand loop
- A loop formed by passing the running end of a line over the standing part.
- f. Turn
- A turn is a component of a knot. Turns can be made around objects, through rings, or around the standing part of the rope itself. Turns come in various forms, distinguished by the number of passes that the rope makes. A turn or single turn requires one pass. The line makes a U-shape through or around the object, or half a revolution. A round turn requires two passes and makes one and a half revolutions. Two round turns adds another pass and revolution.
- g. Bend
- A bend is used to tie two ropes together, as in the Sheetbend. Technically, even the Reef knot is a bend
- h. Hitch
- A hitch is used to tie a rope to a spar, ring or post, such as the Clove hitch. Hitches can also be used to tie one rope ONTO another rope, as in the Rolling hitch.
- i. Splice
- A knot formed by interweaving strands of rope rather than whole lines. More time consuming but usually stronger than simple knots.
- j. Whipping
- A binding knot used to prevent another line from fray.
2. Know how to care for rope.
edit- a. Keep the rope clean.
- b. Always coil a rope before storing it.
- c. Make sure wet rope is dry before coiling it.
- d. Return rope to its proper place after using it.
3. Describe the difference between laid rope and braided rope and list three uses of each.
editIn laid rope, three bundles of fiber or twine are twisted in the same direction, placed close to each other, and allowed to twist together. In braided rope, the fibers are woven together, often around some core material.
Uses of Laid Rope
edit- Repels water
- Able to withstand immense strain.
- Can be spliced with standard techniques
.
Uses of Braided Rope
edit- Works well with pulleys and rigging.
- Spinning (lariats and lassos).
- Decorative knots.
4. Identify the following types of rope
edit- a. Manila
- Manila is a type of fiber obtained from the leaves of the abacá (Musa textilis), a relative of the banana. It is mostly used to make ropes and it is one of the most durable of the natural fibers, besides true hemp. Manila is a coarse, brown fiber, about the same color and feel as a coconut shell.
- b. Sisal
- Sisal is valued for cordage use because of its strength, durability, ability to stretch, affinity for certain dyestuffs, and resistance to deterioration in saltwater. Sisal ropes and twines are widely employed for marine, agricultural (bailing twine), and general industrial use. Sisal fibers are smooth, straight and yellow and can be long or short.
- c. Nylon
- Nylon rope is often white, but any color is possible. It has a smooth, silky feeling to it, and it coils easily. Nylon rope does not float in water. It is a synthetic-fiber rope.
- d. Polypropylene
- Polypropylene rope is most often yellow, though any color is possible. It is often used in marine applications because it floats in water. The rope is sometimes difficult to tie as it is somewhat stiff and brittle. It is a synthetic-fiber rope.
The easiest way to make an initial identification of a rope is to visit a hardware store where rope is sold. The packaging will tell you what the rope is made of. If you want to be sure, buy some of each type (with the labeling) or examine it closely in the store.
5. What are some advantages and disadvantages of synthetic rope?
editAdvantages
edit- Improved abrasion-resistance
- Better UV-resistance
- Lighter
- Length does not vary as much when wet
- Rot-resistant
Disadvantages
edit- Some synthetics do not hold knots well
- More slippery
- Melts when heated
- Stretches more than natural ropes.
6. Do the following to rope
edita. Splice
editA splice is used to join the ends of two ropes and results in the spliced part being about twice as thick as the non spliced part. The short splice retains more of the rope strength than any knots that join rope ends. It is tied using the same techniques as the eye splice (see below).
b. Eye splice
editEye splice |
---|
Use: The eye splice is the best method of creating a permanent loop in the end of multi stranded rope by means of rope splicing. The ends of the rope are tucked (plaited) back into the standing end to form the loop. Originally this splice was described with each end being tucked only about three times. When the splice was made in tarred hemp or cotton this was reasonably safe. With modern synthetic ropes, five complete tucks is a minimum and additional tucks are recommended for critical loads.

c. Back splice
editA back splice (also called an end splice) is a splice where the strands of the end of the rope are spliced directly back into the end without forming a loop. It is used to finish off the end of the rope to keep it from fraying. The end of the rope with the splice is about twice the thickness of the rest of the rope. Begin by unraveling the strands, and tie a crown knot. Then begin splicing the rope onto itself as with the short splice.
d. Finish the end of a rope with a double crown, whipping, or a Matthew Walker's knot.
editDouble crown knot |
---|
Use: A double crown knot is a decorative knot tied on the end of a laid rope to prevent it from unraveling.
How to tie:
|
Common whipping |
---|
Use: The common whipping is the simplest type of whipping knot, a series of knots intended to stop a rope from unraveling. As it can slip off of the rope easily, the common whipping should not be used for rope ends that will be handled. This whipping knot is also called 'wolf' whipping in some parts of the world.
The benefit of a common whipping is that no tools are necessary and the rope does not need to be unlayed. The problem is that it will slide off the end of the rope with little provocation. Other whippings avoid this by interleaving the whipping with the strands of the rope and creating friction with the strands to avoid slipping. Normally a natural fiber rope is whipped with twine. The size of the rope dictates the size of the twine. Any twine can be used, but tarred two strand hemp (marline) is preferred. Artificial-fiber ropes should have their ends fused by heat rather than whipped to prevent unraveling.How to tie:
|
Matthew Walker knot |
---|
Use: A Matthew Walker knot is a decorative knot that is used to keep the end of a rope from fraying. It is tied by unraveling the strands of a twisted rope, knotting the strands together, then laying up the strands together again. It may also be tied using several separate cords, in which case it keeps the cords together in a bundle.

7. Make a six-foot piece of three-strand twisted rope from native materials or twine.
editMaking rope requires some simple apparatus which you can make yourself easily enough. The first apparatus (we'll call it the twister) is used for twisting three strands of twine (or smaller rope). When making the twister, clamp the two boards that form the handles together tightly and drill three holes through both at the same time. This will ensure that they line up. The hook/crank portion of the twister can be made from coat hanger wire. First make the two 90° bends in the center, then pass them through the holes in the handles. Finally, form the hooks on one end and the other 90° bend on the other. (This final bend prevents the crank from slipping out of the holes in the handle).
As the strands are twisted, they will tend to grab one another and twist together. To make rope, this tendency has to be controlled. This is done with a second apparatus (we'll call it the separator). It consists of a board with three holes drilled in it, forming the points of an equilateral triangle. These points should be at least six inches away from one another, and should be large enough to pass the strands of twine through.
To make rope, cut three pieces of twine about 33% longer than the desired rope. Pass each strand through a hole in the separator, then tie a non-slip loop in the end of each (a figure-eight on a bight works well for this). We will call this end of the strands the free end. Slip these loops over a hook of some sort, and pull the strands straight. Bunch the ends opposite the loops together, and tie them off, again in a loop (and again, a figure-eight on a bight works well for this). We will call this end the bound end. Make sure that the three strands are the same length from one loop to the other. Hand the bound end to a helper, then attach the loops on the free end to the hooks on the twister. Pull the twister away from the bound end (still affixed firmly to another hook) until the strands are straight and tight. Then slide the separator towards the common end. Start cranking the twister so that the hooks rotate. As you crank, your helper will allow the three strands on his side of the separator to twist together. As they do this, the helper will slide the separator towards you, going only as fast as the strands bind to one another. Be careful to keep the strands tight as you do this so that they do not bind to one another on your end of the separator. Continue twisting until the separator reaches the twister. Then tie a knot in the free end of the rope, unhook it from the twister, and slide the separator off. Tie a stopper knot, or bind the end with tape. Then cut off the few inches of untwisted strand that remain (or make a back splice). Finish the opposite end in the same manner. Voila! You now have a rope!
8. From memory tie at least 20 of the following knots and know their common uses and limitations. Demonstrate how they are used.
editAnchor bend
editAnchor bend |
---|
Use: The Anchor Bend is a knot used for attaching a rope to a ring or similar termination. The round turn and tight application help keep the rope from chafing.
How to tie:
|
Bowline
editBowline |
---|
Use: This knot doesn't jam or slip when tied properly. It can be tied around a person's waist and used to lift him, because the loop will not tighten under load. In sailing, the bowline is used to tie a halyard to a sail head.
How to tie:
|
Bowline on a bight
editBowline on a bight |
---|
Use: This makes a secure loop in the middle of a rope which does not slip.
How to tie:
|
Butterfly loop or Alpine butterfly knot
editAlpine butterfly |
---|
Use: The Butterfly Loop has a high breaking strength and is regarded by mountaineers as one of the strongest knots to attach climbers to the middle of a rope, such that they have room to move around even when the main rope goes tight, and they can be supported in either direction from the main rope. The loop is typically attached to a climbing harness by carabiner.
It can also be used to isolate a worn section of rope, where the knot is tied such that the worn section is used for the center of the loop.
|
Carrick bend
editCarrick bend |
---|
Use: The Carrick bend is used for joining two lines. It is particularly appropriate for very heavy rope or cable that is too large and stiff to easily be formed into other common bends. It will not jam even after carrying a significant load or being soaked with water. The Carrick bend's aesthetically pleasing interwoven and symmetrical shape has also made it popular for decorative purposes.
In the interest of making the Carrick bend easier to untie, especially when tied in extremely large rope, the ends may be seized to prevent the knot from collapsing when load is applied. This practice also keeps the knot's profile flatter and can ease its passage over capstans or winches. The ends are traditionally seized to their standing part using a Round seizing. For expediency, a series of double constrictor knots, drawn very tight, may also be used. When seizing the Carrick bend, both ends must be secured to their standing parts or the bend will slip. WARNING: The Carrick bend is generally tied in a flat interwoven form shown above. Without additional measures it will capsize (collapse) under load into a secure and stable, although bulky, form. If the knot is allowed to capsize naturally under tension, considerable slippage of line through the knot can occur before tightening. The knot should be upset carefully into the capsized form and worked up tight before actual use.

Cat's paw
editCat's paw |
---|
Use: The Cat's paw is used for connecting a rope to an object.
How to tie:
Form a bight in the middle of the line, and pull it back over itself like a girth hitch. This forms two loops, turned in opposite directions. Give each loop one more full turn in the direction that will tend to tighten it (the wrong direction will undo the loop completely). Pass both loops over the hook, rail or post and pull tight, taking care to push the bight up snugly against the turns.
If working end of the line has an eye in it, and the standing end is accessible, the knot can be tied to a closed ring, another eye, or a rail with inaccessible ends, as follows. Pass the eye around the ring or rail, then pass the standing end through its own eye (this effectively forms a girth hitch). Then pass the standing end through the eye again, and pull up tight, taking care to push the bight up snugly against the turns. When using the cat's paw to join two eyes, this process may be repeated several times to give several turns - as many as five in a fine fishing monofilament. Then when tightened, instead of pulling the bight up against the turns, both eyes are pulled equally, to make neat coils of turns in both eyes, meeting halfway between them. |
Clove hitch
editClove hitch |
---|
Use: This knot is the "general utility" hitch for when you need a quick, simple method of fastening a rope around a post, spar or stake.
How to tie:
|
Constrictor knot
editConstrictor Knot |
---|
Use: The Constrictor knot is one of the most effective binding knots. Simple and secure, it is a harsh knot which can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn. It is a very effective knot for constructing a pilot's ladder, as it will not slip when tied around wooden rungs.
How to tie:
WARNING: The Constrictor knot's severe bite, which makes it so effective, can damage or disfigure items it is tied around.
|
Crown knot
editCrown Knot |
---|
Use: Used a component in a back splice and in the double crown knot. Can be used to temporarily prevent the ends of a laid rope from unraveling.
How to tie:
|
Double bow
editDouble bowline |
---|
How to tie:
|
Double sheet bend
editDouble sheet bend |
---|
Use: The double sheet bend or double becket bend is a strong knot used to tie two ropes (usually of different thicknesses or rigidity) together. It is a doubled version of the sheet bend.
How to tie:
WARNING: As with the standard sheet bend, the two free ends should end up on the same side of the knot. If they do not, a left-handed double sheet bend results, which is much weaker.
|
Figure eight
editFigure Eight |
---|
Use: This knot is ideal for keeping the end of a rope from running out of tackle or pulley.
How to tie:
|
The fisherman's knot is a bend (a knot for joining two lines) with a symmetrical structure consisting of two overhand knots, each tied around the standing part of the other. Other names for the fisherman's knot include: angler's knot, English knot, halibut knot, waterman's knot.
Fisherman's bend
editFisherman's knot |
---|
Use: The Fisherman's knot is a specialized bend. It consists of two overhand knots wrapped around each other. It works well for joining thin, stiff, or slippery lines.
It requires little dexterity to tie, so is often used in stubborn materials. When tightened, it becomes fairly compact, and the free ends can be cropped very close to the knot. These qualities make it very useful for fishing line--it is less likely to jam a fishing rod than many other bends, and is easier to tie with cold, wet hands.
How to tie:
|
Fisherman's loop
editFisherman's loop |
---|
Use: The fisherman's loop makes a non-slip loop at the end of a rope.
How to tie:
|
Halter hitch
editHalter hitch, Hitching tie |
---|
Use: The halter hitch, sometimes called a hitching tie is used to tie the lead rope, which is attached to a horse's halter (or to a boat), to a post or hitching rail. The benefit of the halter hitch is that it can be released by pulling on one end of the rope. Even if there is tension on the horse-side of the rope it can still be release with ease.
How to tie:
|
Hunter's bend
editHunter's bend |
---|
Use: The Hunter's bend (aka Rigger's bend) is used to join two lines. It consists of interlocking overhand knots, and can jam under moderate strain.
Hunter's bend is one of the most recent knots to be discovered. It appeared on the front page of The Times in 1978 and was credited to Dr. Edward Hunter. Dr. Hunter used it for years to tie broken shoelaces before discovering its originality through a friend in the 1970s. When it appeared on the front page, it led to much publicity for the knot and also to the foundation of the International Guild of Knot Tyers. However, the knot was presented in Knots for Mountaineering by Phil Smith ca. 1956.
|
Lariat or Bowstring knot
editLariat |
---|
Use: A lariat knot is the loop knot commonly used in a lasso. Its round shape, especially when tied in stiff rope, helps it slide freely along the rope it is tied around.
How to tie:
|
Lark's head
editLark's head |
---|
Use: The lark's head is a knot (specifically, a hitch). Also called a cow hitch, it comprises two half-hitches tied in opposing directions. The cow hitch is often used to connect loop-ended lanyards to handheld electronic equipment, since it can be tied without access to the ends of the fastening loop.
How to tie:
|
Man harness knot
editMan harness knot |
---|
Use: The Man harness is a knot with a loop on the bight for non-critical purposes. This knot is used when multiple people are to pull a load. Typically one end of the rope is tied to a load, and one man harness knot per puller will be tied along its length. Each loop is then pulled by a different person.
How to tie:
WARNING: The Man harness knot must have the loop loaded or it will slip and contract easily.
|
Miller's knot
editMiller's knot |
---|
Use: A Miller's knot (also Sack knot or Bag knot) is a binding knot used to secure the opening of a sack or bag. Historically, large sacks often contained grains; thus the association of these knots with the miller's trade. Several knots are known interchangeably by these three names. Several variations are shown here.
|
Packer's knot
editPacker's knot |
---|
Use: The Packer's Knot is a binding knot usually used in smaller line.
This knot is sometimes used in baling and in parcel tying.
How to tie:
|
Pipe hitch
editPipe hitch |
---|
Use: The pipe hitch is used for hoisting tubular objects (such as pipes).
How to tie:
|
Prusik knot
edit
Sheepshank
editSheepshank |
---|
Use: The sheepshank knot is used to shorten a length of rope. It comes undone easily unless it is under tension.
WARNING: Keep this knot under tension or it will come untied.
|
Sheet bend
editSheetbend |
---|
Use: The sheet bend knot is excellent for joining two ropes together, especially if the two ropes are not the same size. When tied properly, it will not come undone, and it is easy to untie. It is very similar to the bowline.
How to tie:
|
Slip knot
editSlip knot |
---|
Use: A slip knot is one that will tighten under load, and which can be easily untied by pulling on the running end. This knot is typically a component of more complicated knots, and is generally not used by itself.
How to tie:
WARNING: If tied as shown in the illustration, the running end (on the right) will pull through the loop if even the slightest load is applied to the standing end (on the left). If one reverses the standing end and running ends in the illustration, the knot is far more stable. As shown, the knot will hold a load on the running end, but not on the standing end.
|
Slipped half hitch
editSlipped half-hitch |
---|
Use: A slipped half-hitch is a knot used to attach a line to a rod or bar. It does not provide great strength compared to some other knots, but it can be tied relatively quickly and released very easily. These characteristics mean that it is used on square-rigged ships for securing the gaskets that bind stowed sails to the yards.
How to tie:
WARNING: Never use this knot in a critical situation. It comes untied at the slightest provocation.
|
Slipped sheet bend
editSlipped sheet bend |
---|
Use: The slipped sheet bend is used in non-critical situations for temporarily joining two ropes.
How to tie:
WARNING: The slightest tug on the running end will untie this knot instantly - even if the knot is under load.
|
Square knot
editIt is used for the Basic Rescue. ( See basic rescue honor)
Square Knot |
---|
Use: Also known as a Reef knot, the Square Knot is easily learned and useful for many situations. It is most commonly used to tie two lines together at the ends. This knot is used at sea in reefing and furling sails. It is used in first aid to tie off a bandage or a sling because the knot lies flat.
How to tie:
WARNING: Do not rely on this knot to hold weight in a life or death situation. It has been known to fail.
|
Stevedore's knot
editStevedore knot |
---|
Use: The Stevedore knot is a stopper knot, often tied near the end of a rope. It is more bulky and less prone to jamming than the closely related figure-eight knot. This knot is excellent for anchoring a tarp. Pass the end of the rope through a tarp's grommet, tie a stevedore, and anchor the other end with a taut-line hitch. Its added bulk prevents it from pulling through the grommet.
How to tie:
|
Strangle knot
editStrangle knot |
---|
Use: The Strangle knot is a simple binding knot. Similar to the constrictor knot, it also features an overhand knot under a riding turn. The difference is that the ends emerge at the outside edges, rather than between the turns as for a constrictor. This knot is actually a rearranged double overhand knot and makes up each half of the double fisherman's knot.
When tightened, it is very slip-resistant. It is ideal for constructing a pilot ladder (like a rope ladder, but with wooden rungs).
|
Surgeon's knot
editSurgeon's knot |
---|
Use: The surgeon's knot is similar to a square knot, except that the first stage is doubled. This helps the knot stay tight while it is being tied.
|
Taut-line hitch
editTaut-line hitch |
---|
Use: The Taut-Line Hitch is an adjustable loop knot for use on lines under tension. It is useful when the length of a line will need to be periodically adjusted in order to maintain tension. It is made by tying a Rolling hitch around the standing part after passing around an anchor object. Tension is maintained by sliding the hitch to adjust size of the loop, thus changing the effective length of the standing part without retying the knot. When under tension, however, the knot will grip the cord and will be difficult to cause to slip.
It is typically used for securing tent lines in outdoor activities involving camping, by arborists when climbing trees, for creating adjustable moorings in tidal areas, and to secure loads on vehicles. A versatile knot, the Taut-line hitch was even used by astronauts during STS-82, the second Space Shuttle mission to repair the Hubble Space Telescope. How to tie:
