How to tie A Sheepshank ( proper method ), Rusa scouts standard requirement

Function: to shorten a piece of rope/string to the desired length
The sheepshank is a type of knot (or, more accurately unknot) that is used to shorten a rope or take up slack. This knot is not stable. It can easily just fall apart under too much load or too little load.

The knot has several features which allow a rope to be shortened: * It provides two loops, one at each end of the knot which can be used to pass another rope through * The knot remains secure under tension; the coarser the rope the more secure it is (see Disadvantages, below) * The knot falls apart easily when tension is removed

Sheepshank knots are typically used for securing loads to trucks or trailers, and in sailing applications.
disadvantage: The sheepshank was developed before the use of modern "slippery" synthetic ropes. Constructed from such ropes, under load, it can fail. It is strongly advised that an alternative knot be used.

Instructions ;using the middle of the string/rope, form 3 loops as seen in the video, the first loop with the end facing outward and the second loop's end facing inwards and for the third loop with the end of the string forming the loop facing outwards as seen in the video
Next, place the middle loop into the loop on the left and right and pull taunt.
( not easy to describe how to tie, please try to observe the video closely to learn how to tie )

Wikpedia's Instructions : * Pull a section of rope back and lay it alongside the rope, so that the rope forms a Z approximately 20 cm long. * Flatten the Z so that there are 3 sections of rope lying alongside each other, with two U-bends where the rope reverses direction.
* At each U-bend, grasp the U-bend in one hand, thus holding two of the rope sections. With the other hand form a small loop in the remaining section and draw it over the U-bend so that the loop forms a half hitch and stays there if the free end of the rope is pulled taut. Many people draw the small loop over facing the wrong way at least half of the time. Instead, make with the U a half-hitch around the other part, by tucking through, then pull the U straight.
* Repeat at the other U-bend.

An alternative method for quickly constructing a sheepshank is as follows: * Create a simple loop in the rope, so that the (left) leading end is on top of the (right) trailing end of the loop. * Repeat this process further down the rope to create 3 total loops that overlap slightly (similar to a venn diagram with three circles). * Reach through the outer two loops and grab either side of the middle loop and pull outward while also keeping the rest of the rope slightly taut. * Once the middle loop is pulled through the outer loops, pull on the free ends of the rope to secure.

The result is a flattened loop which is held at each end by a half hitch. If the sides of the flattened loop are pulled away from each other, the flattened loop ends pull out of the half hitches and the knot falls apart, but if the free ends are pulled taut then the knot remains secure.

  • Only a halfwits couldn't follow that, thanks;-)

  • I GOT A DAMM STRAIGHT ROPE!!!!!!!

  • video is crap. REDO !

    and a sheepshank is generally used to isolate a damaged part of the rope or to shorten a rope. In your demonstration you have hardly displayed that. Some one with no knowledge on what it's supposed to look like won't know what you're trying to show.

  • horrible video. re-do!
