Knot Masters Troop 90
Knot Masters Troop 90 1. Every Scout and Scouter joining Knot Masters will be given a test by a Knot Master and will be assigned the appropriate starting rank and rope. Ropes shall be worn on the left side of scout belt secured with an appropriate Knot Master knot. 2. When a Scout or Scouter proves he is ready for advancement by tying all the knots of the next rank as witnessed by a Scout or Scouter of that rank or higher, he shall trade in his old rope for a rope of the color of the next rank. KNOTTER (White Rope) 1. Overhand Knot Perhaps the most basic knot, useful as an end knot, the beginning of many knots, multiple knots make grips along a lifeline. It can be difficult to untie when wet. 2. Loop Knot The loop knot is simply the overhand knot tied on a bight. It has many uses, including isolation of an unreliable portion of rope. 3. Square Knot The square or reef knot is the most common knot for joining two ropes. It is easily tied and untied, and is secure and reliable except when joining ropes of different sizes. 4. Two Half Hitches Two half hitches are often used to join a rope end to a post, spar or ring. 5. Clove Hitch The clove hitch is a simple, convenient and secure method of fastening ropes to an object. 6. Taut-Line Hitch Used by Scouts for adjustable tent guy lines, the taut line hitch can be employed to attach a second rope, reinforcing a failing one 7. -
The Great Knot Competition
Outdoor Education 9 The Great Knot Competition Date of competition: ________________________ Learn to accurately and quickly tie useful knots from memory! The student with the most winning times on the knots will win the competition, with a second runner up. Incorrectly tied knots or memory aids will disqualify quickest times. 1st Place - First choice of chocolate bar 2nd Place - Chocolate bar Knots to be Timed: 1. Square Knot (Reef Knot) The square knot can join 2 ropes of the same size. It is the first knot we learn to make with our shoelaces. It looks like a bow and is hugely unreliable. Its breaking strength is only 45% of the line strength. The simple and ancient binding knot is also known by the names Hercules, Herakles, flat, and reef knots. It helps to secure a line or rope around an object. It creates unique designs of jewelry. 2. Figure 8 Follow Through Based on the figure 8 knot, figure 8 follow through knot is one of the ways of tying a figure 8 loop the other one being the figure 8 on a bight. It secures the climbing rope to a harness thereby protecting the climber from an accidental fall. 3. Bowline The bowline (pronunciation “boh-lin”) is a knot that can itself be tied at the middle of a rope making a fixed, secure loop at the end of the line. It retains about 60% of the line strength and has a knot efficiency of 77%. 4. Barrel Knot It is a friction knot (or slip knot) meaning that it will self-tighten around the object it is tied to when loaded. -

The Scrapboard Guide to Knots. Part One: a Bowline and Two Hitches
http://www.angelfire.com/art/enchanter/scrapboardknots.pdf Version 2.2 The Scrapboard Guide to Knots. Apparently there are over 2,000 different knots recorded, which is obviously too many for most people to learn. What these pages will attempt to do is teach you seven major knots that should meet most of your needs. These knots are what I like to think of as “gateway knots” in that once you understand them you will also be familiar with a number of variations that will increase your options. Nine times out of ten you will find yourself using one of these knots or a variant. The best way to illustrate what I mean is to jump in and start learning some of these knots and their variations. Part One: A Bowline and Two Hitches. Round Turn and Two Half Hitches. A very simple and useful knot with a somewhat unwieldy name! The round turn with two half hitches can be used to attach a cord to post or another rope when the direction and frequency of strain is variable. The name describes exactly what it is. It can be tied when one end is under strain. If the running end passes under the turn when making the first half-hitch it becomes the Fisherman’s Bend (actually a hitch). The fisherman’s bend is used for applications such as attaching hawsers. It is a little stronger and more secure than the round turn and two half-hitches but harder to untie so do not use it unless the application really needs it. -

Member: California State Fire Training • Rope Rescue Technician Curriculum Development Working Group • Confined Space Technician Working Group Rescue Knot Efficiency Revisited In 1987 personnel from CMC Rescue performed tests on a variety of knots commonly used in rescue systems to determine their efficiency. The purpose of testing was as preparation for the First Edition of the CMC Rope Rescue Manual and for presentations at various industry events. Prior to this time there had been similar testing on climbing knots, but the rope used was three-strand laid rope (Goldline) and there were no details of the testing conditions or methods used, so the results were not considered repeatable or of unknown value to rescuers using low stretch ropes. Our testing was done at Wellington Puritan, a large rope manufacturer in Georgia, but no details were given about their test machine. There wasn’t any Cordage Institute #1801 standard for test methodology at the time, though the report does state that Federal Test 191A Method 6016 was used. -

Fishing Knots Allow You to Properly Tie Your Line to Your Hook, Lure and Other Tackle
KNOTS YOU NEED TO KNOW Fishing knots allow you to properly tie your line to your hook, lure and other tackle. These knots have been developed and tested thoroughly to assure tying ease and strength. Each knot has a specific purpose. Before you learn any new knot, consider the following: • The right knot is important. You want the strongest knot possible so that you don’t lose the fish. A simple overhand knot weakens line by about 50 percent. • Practice tying knots. Take a length of fishing line, a hook with the point cut off or buried into a cork, and practice. Practice until you can tie each knot correctly. • Wet knots with saliva as you pull them tight. This prevents damage to the line and allows the knot to pull tight. • Pull knots tight to prevent slippage. • Trim knots closely with a nail clipper. A good knot, pulled tight, will not come loose. Close trimming prevents the knot from catching snags or weeds. Do not burn the tag end – heat damages the line and knot. • Knots have their own terminology. The "tag end" (sometimes called the "working end") is the end of the line used to tie the knot. The "standing end" is that part of the line coming from your fishing reel. • Leave a foot or more of the "tag end" of line for tying knots so that you can tie them properly. • Pull up all ends when tightening the knot. With some knots this will be only the standing end and tag end; with other knots it might be three or four ends. -
Revision of Commonly Used Loop Knots Efficiencies
ACTA PHYSICA POLONICA A No. 3 Vol. 138 (2020) Revision of Commonly Used Loop Knots Efficiencies J. Šimona;∗, V. Dekýšb and P. Palčekc aDepartment of Applied Mathematics, Faculty of Mechanical Engineering, University of Žilina, Univerzitná 8215/1, 010 26 Žilina, Slovakia bDepartment of Applied Mechanics, Faculty of Mechanical Engineering, University of Žilina, Univerzitná 8215/1, 010 26 Žilina, Slovakia cDepartment of Materials Engineering, Faculty of Mechanical Engineering, University of Žilina, Univerzitná 8215/1, 010 26 Žilina, Slovakia Received: 15.11.2019 & Accepted: 24.04.2020 Doi: 10.12693/APhysPolA.138.404 ∗e-mail: [email protected] In a number of professions, human life hangs on a knotted rope. However, until now only a poor attention of scientists has been paid to the properties of knots. The main objective of the presented research is to provide an in-depth revision of commonly used loop knot efficiencies employing modern experimental technologies and correct statistical processing. In the first part of the paper, the common mistakes in the available information sources were pointed out and the correct way of assessing the loop knot efficiency was proposed. Subsequently, correct statistical calculus was derived to evaluate mean knot efficiency and confidence interval. Efficiencies of eight commonly used loop knots loaded in several geometries were precisely measured, evaluated, and analyzed. Special attention was paid to avoid misleading conclusions based on experiments of low statistical power. Loop knot efficiency is not a constant, but it depends at least on the static breaking strength of a rope. The process of knot breakage was recorded by high-speed infrared thermal imaging.
