Investiture Achievement Connection: This Honor is related to the Investiture Achievement requirements for Outdoor Living which require Friends to tie and know the practical use of 10 knots, Companions to tie and know the practical use of 20 knots, Explorers to earn the Knot Tying Honor, while Guides must teach the Knot Tying Honor. Master Guides are also required to earn or hold the Knot Tying Honor.

Investiture Achievement Tie Ins and Teaching Tips

Knot tying is an important part of Pathfindering with tie ins to Investiture Achievement and many other honors such as the various Camping Honors, Rock Climbing, Pioneering and others.

Friends are required to tie and know the practical use of 10 knots
Companions are required to tie and know the practical use of 20 knots
Explorers must earn the Knot Tying Honor
Guides must, under the guidance of an adult staff member, teach the Knot Tying Honor
Master Guides are required to earn or hold the Knot Tying Honor.

An effective way to teach knots in a club setting is to have the staff and the older Pathfinders (the ones who already have the Knot Tying Honor) each teach a single knot at a knot tying station. The Pathfinders who are learning the knots will rotate through the stations. After a set time, ring a bell to signal that it's time to rotate, and do not allow the students to rotate until the bell rings (otherwise, they will all gravitate to the same table).

Using this approach, each of the teachers need only learn a single knot well enough to teach it, and the students will have a chance to receive one-on-one instruction for every knot. Allow at least seven or eight minutes per station. You can do this over more than one meeting if necessary, and you can involve the entire club at once rather than only a single unit.

Prior to the meeting, the rope may be cut to the proper length. Some instructors consider cutting rope during a meeting a waste of valuable teaching time, while others use it as an opportunity to teach proper binding of the rope. To prevent the cut rope from unravelling, wrap a small piece of duct tape around it before you make the cut - then cut the tape in half. This will save time, as it binds both ends of the cut in one shot.

The length of each rope should be suited to the knot it will be used for. Note that a figure eight knot does not require as much rope as a timber hitch, and that it is impossible to tie a knot on a rope that it too short to hold it. Conversely, using too much rope for small knots is a waste of good rope (and money!). Remember that the amount of rope wasted on each knot will be multiplied by the number of students.

A good way to determine proper rope length is to tie the desired knot using a long piece of rope, cut it, and then untie it. That's how long it needs to be. Cut as many of that length as you will have students, put them in a plastic baggie, and label the bag. You may have the knot instructors cut their own ropes, or you may have a squad of TLT's do this. Or you could do it yourself (but that would be depriving your TLT's and/or instructors of a valuable experience).

Two knot tying stations can easily share an eight foot table and a hot-melt glue gun - assuming the students will be mounting the knots on a board as they tie them. If you are organized and have the space, you can store their knot boards from year to year and let them add to it each year. By the time they are in the Ranger class, they will appreciate not having to tie 25 knots all at once.

A good knot board can be made from a length of lumber - 24"x12"x3/4" makes a good sized board if you are using quarter-inch diameter rope. A stick can be fastened along the edge of the board to make a convenient place to tie the hitches.

For a professional-looking knot board, prepare labels for the knots using a label maker. Again, this is something that should be done prior to the meeting, as making labels and distributing them is not an effective use of instruction time. You should also make labels with each student's name (or have students label their boards neatly) so that they will be able to find their knot boards in the future and to prevent disputes over knot board ownership. You might also consider labeling the knot boards before they are given to the students (and before the knots are tied), as this makes it easy to figure out which knots the student still needs to learn.

1. Define the following terms:

It'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

a. Bight: The term bight refers to any curved section, slack part, or loop between the two ends of a rope,
b. Running end: The free end of the rope, usually shorter. 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: Adventist Youth Honors Answer Book/Knot/Turn
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 fraying.

2. Know how to care for rope.

3. Describe the difference between laid rope and braided rope and list three uses of each.

In 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

Repels water.
Able to withstand immense strain.
Can be spliced with standard techniques.

Uses of Braided Rope

Works well with pulleys and rigging.
Spinning (lariats and lassos).
Decorative knots.

4. Identify the following types of rope:

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?

Advantages

Improved abrasion-resistance
Better UV-resistance
Lighter
Length does not vary as much when wet
Rot-resistant

Disadvantages

Some synthetics do not hold knots well
More slippery
Melts when heated
Stretches more than natural ropes.

6. Do the following to rope:

a. Splice

A splice (short splice or long 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

Adventist Youth Honors Answer Book/Knot/Eye splice

c. Back splice

A 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.

7. Make a six-foot piece of three-strand twisted rope from native materials or twine.

8. From memory tie at least 20 of the following knots and know their common uses and limitations. Demonstrate how they are used.

9. Make a knot board showing 25 or more knots.
