Ashley's Stopper Knot or Oysterman's Stopper or ABOK # 526 Tying a "stopper knot" at the end of the rope can help prevent the end from slipping through the knot due to a heavy load or a series of jerks on the rope. To tie this knot, first tie a Slip Knot (picture 1), then bring the end of the rope back through the loop (pictures 2 and 3). If you follow the pictures then you should end up with a nice, bulky knot (picture 4). PDFmyURL.com -1 -2 -3 -4 According to Budworth, "Clifford W. Ashley, whose monumental work The Ashley Book of Knots is every knot enthusiast's bible, devised this knot sometime before 1910." (The Complete Book of Knots, p.32). 2. -

The Most Useful Rope Knots for the Average Person to Know Bends

Site Map Home Knots Index Single-Loop Knots Multi-Loop Knots Hitches Bends (this page) Miscellaneous Knots Decorative Knots Bends (and other ways of tying ropes together) When two ends of rope (from the same rope or from different ropes) are tied together with a single knot, the knot is referred to as a "bend." If you don't tie knots in rope very often then it might be difficult to remember which knot to use, and how to tie it properly, when you need to tie two ends of rope together securely. Therefore, it's a good idea to learn one or two good bends which you can remember easily, and my preferences are the Fisherman's Knot and the Alpine Butterfly Bend, although I'm trying out the Double Harness Bend more and more lately (which can easily be turned into a Reever Knot ). Practice tying your favorite knots periodically (from different angles) so that you'll remember how to tie them when you need them. Here are some bends: PDFmyURL.com 1. -
The Reef Knot Family (Reef, Thief, Granny & Grief)
7/17/2010 The Reef Knot Family (Reef, Thief, Gra… HOME The Reef Knot Family Bowline Knot Diagram Waterproof Plastic Cards Show All Best Knots - Fishing & Rope Knots. The reef knot or square knot is notably dangerous if misused. The square knot or reef knot www. k n o tca rd s . co m should only be used as a binding knot where it lies tightly against the surface of that which it binds and cannot move. Unfortunately, it is wrongly used as a bend where it has killed many. Used as a bend, joining two ropes, it can unexpectedly spill. What's worse is that it often times holds firm so as to give people a false sense of security, thus setting the stage for tragedy when it shows its true unstable nature. Even minute differences in rope size, texture, or stiffness in what most would consider "normal" rope, will greatly amplify the insecurity of a reef knot used as a bend. It's also very vulnerable to spill when being pulled around corners or over rough terrain, especially if a free end gets snagged. If you know how to tie your shoes, you probably use a "slipped" form of the square knot or the granny knot. The reef knot is handy as a binding knot and can often be undone by firmly jerking in opposite directions the free end and standing part of one of the "U" shapes that interlock to make this knot. A surgeon's knot or ligature knot is just a square knot with a double tuck on the first half of the knot instead of a single tuck. -

Site Map Home Knots Index Single-Loop Knots (this page) Multi-Loop Knots Hitches Bends Miscellaneous Knots Decorative Knots Single-Loop Knots A single-loop knot is useful when you need to throw a rope over something such as a post (to tie up a boat, for example), or when you need to attach something to a loop of rope (as in rock climbing), etc. If you don't tie knots in rope very often then it might be difficult to remember which knot to use, and how to tie it properly, when you need a loop. Therefore, it's a good idea to learn one or two good knots which you can remember easily. For a mid-line loop or an end-line loop, my current preference is the double-wrapped Flying Bowline, although sometimes I use the Alpine Butterfly. When I need to pass a rope around an object and tie off the end, I usually use the Adjustable Grip Hitch. I've never had problems with slipping or jamming using these knots, but this doesn't mean that they're the best knots for you to use. -
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. -

Troop 396 Knot Book 11/1/02
Troop 396 Knot Book 11/1/02 This book may seem a little unnecessary to many people. With all of the great books about knots already on the shelves, why would anyone want to make their own? There are three reasons. First, there is a lot of incorrect and vague information out there, some of which is even found in official Boy Scout publications. Since a knot is, to coin a phrase, either exactly right or hopelessly wrong, there is no room for ambiguity At times human life may literally hang in the balance, relying only on the strength of a rope and the precision of some basic knots as a safeguard against arriving at the bottom of a cliff too quickly and in a pulpy red heap. Second, these graphics were developed as teaching aids for Cub Scouts, boys with small hands and fleeting attention. It seemed reasonable that the task would be easier with drawings that were very clear and very large. In fact the guiding principle behind this book was that the pictures be large enough to lay on a table with the knot tied right on top; sort of like tracing a drawing. In practice that has dubious value. It works well for some boys, not at all for others. When one ties on top of a picture, one cannot see the picture, at least not very well. The lines in the graphics are 3/8” wide and we used 1/4” rope, so it wasn’t as bad as it may seem. Still it was easier for some boys to tie “in the hand” anyway.
