Knot

• A knot is a method for fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or more segments of rope, string, webbing, twine, strap or even chain interwoven so as to create in the line the ability to bind to itself or to some other object - the "load".

Page 3: SIMPUL & IKATAN

Webbing• Webbing is a strong fabric woven as a flat strip

or tube of varying width and fibers often used in place of rope. It is a versatile component used in climbing, furniture manufacturing, automobile safety, auto racing, towing, parachuting, military apparel, and many other fields.

Twine

• Twine is a strong thread or string composed of two or more smaller strands or yarns twisted together.

Page 5: SIMPUL & IKATAN

Strap

• A strap, sometimes also called strop, is an elongated flap or ribbon, usually of fabric or leather.

Categories

• Knots may belong to more than one category.• Bend 

– A knot uniting two lines. A bend knot is a knot used to join two lengths of rope.

• Binding – A knot that restricts object(s) by making multiple winds. A

binding knot is a knot that may be used to keep an object or multiple loose objects together

• Coil – Knots used to tie up lines for storage.

• Decorative knot – A complex knot exhibiting repeating patterns often constructed

around and enhancing an object.

Page 7: SIMPUL & IKATAN

Categories

• Hitch – A knot tied to a post, cable, ring, or spar.

• Lashing – A knot used to hold (usually) poles together.

• Loop – A knot used to create a closed circle in a line.

• Plait (or Braid)– A number of lines interwoven in a simple

regular pattern.

Page 8: SIMPUL & IKATAN

Categories

• Slip (or Running) – A knot tied with a hitch around one of its parts,

contrasted. with a loop, which is closed with a bend. A slip knot can be closed, a loop remains the same size.

• Seizing – A knot used to hold two lines or two parts of the same

line together.

• Sennit – A number of lines interwoven in a complex pattern.

Page 9: SIMPUL & IKATAN

Categories

• Splice – A knot formed by interweaving strands of rope rather

than whole lines. More time consuming but usually stronger than simple knots.

• Stopper – A knot tied to hold a line through a hole.

• Trick – A knot that is used as part of a magic trick, a joke, or

a puzzle. • Whipping 

– A binding knot used to prevent another line from fraying.

Clove hitch

• It consists of two identical half hitches made successively around an object. It is most effective used as a crossing knot. Although it can be used as a binding knot, it is not particularly secure in that role.

• It should not be relied on with rope that is thin or very slippery, as it can work itself loose, especially under a swinging or rotating load.

• However, for this very reason, the knot is useful in situations where the length of the running end needs to be adjustable.

• It can also jam and become difficult to untie under some situations.

Lashing

• A lashing is an arrangement of rope used to secure two or more items together in a somewhat rigid manner.

• Lashings are most commonly applied to timber poles, and are commonly associated with the scouting movement and with sailors.

Page 16: SIMPUL & IKATAN

Square lashing

• Square lashing steps;– Begin with a clove hitch on the vertical pole beneath

the horizontal pole and tuck the loose end under the wrapping.

– Wrap in a square fashion about three times around the poles.

– Frap two or three times, pulling often to work the joint as tight as possible.

– Tie two half hitches around the horizontal pole – Cinch the half hitches into a clove hitch, an additional

clove hitch may be added if desired.

Diagonal lashing

• The timber hitch is a knot used to attach a single length of rope to a piece of wood. This knot is easily undone after use.

– Begin with a timber hitch around the juncture of the two poles.

– Make three turns in each direction - tightening steadily as you go.

– Make two frapping turns, tightening the joint as much a possible.

– To end, make two half hitches – Cinch the half hitches into a clove hitch

Tripod lashing

• To bind three poles together, for the construction of a tripod. ---- To bind three poles together that contact at the same point in a structure

Sheer lashing

• A sheer lashing is often used to bind adjacent poles together. It is also a good way to reinforce a broken or weak pole. The frapping turns used to tighten the lashing may be omitted and replaced with wedges inserted between the poles.

Slip knot

• The former kind are generally created by attaching a rope to itself, creating a loop which can be tightened later.

Reef knot

• The reef knot or square knot is a common and simple binding knot.

• To tie a reef knot, tie a left-handed overhand knot and then a right-handed overhand knot or vice versa.

Page 32: SIMPUL & IKATAN

Stopper knot

• The term stopper knot (or simply stopper) has three distinct meanings in the context of knotting and cordage.

Page 33: SIMPUL & IKATAN

Constrictor knot

• 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.

• The Double constrictor knot is an even more robust variation having two riding turns.

Cow hitch

• The cow hitch comprises two half-hitches tied in opposing directions.

• When both the standing parts of the rope are available, the cow hitch can be tied in the following manner:– Form a bight and pass it through the ring from the underneath. – Pull the head of the bight downwards, and reach through it,

grabbing both standing parts of the rope. – Pull both standing parts of the rope through the bight. – 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.

Taut-line hitch - Adjustable hitch

• 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.

• The Taut-line hitch is an adjustable loop knot for use on lines under tension.

• 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.

• This version is the one most often seen named "Taut-line hitch".

• The name Tent hitch is used in some older scouting manuals

Midshipman's hitch

• This version is considered the most secure but may be more difficult to adjust after being heavily loaded.

Fisherman's knot

• It consists of two overhand knots wrapped around each other.

• 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.

Double fisherman's knot

• Use the double fisherman's knot to tie together two ropes of unequal sizes.

• This knot and the triple fisherman's knot are the variations used most often in rock climbing, but other uses include search and rescue.

Sack knot

• A Miller's knot (also Sack knot or Bag knot) is a binding knot used to secure the opening of a sack or bag.
