Editing Constrictor knot (section)

==Tying method==
The method shown below is the most basic way to tie the knot around a post (that is, using a working end).<ref name="Grog Instrument">{{cite web|title=Constrictor Knot: Instrument Method|url=http://www.animatedknots.com/constrictorinstrument/|access-date=4 May 2014}}</ref>

#Make a turn around the object and bring the working end back over the standing part.
#Continue around behind the object.
#Pass the working end over the standing part and then under the riding turn and standing part, forming an overhand knot under a riding turn.
#Be sure the ends emerge between the two turns as shown.  Pull firmly on the ends to tighten.

There are also at least three methods to tie the constrictor knot [[in the bight]] and slip it over the end of an object to be bound.

===Twisting method=== 
Using both hands when the end of the object to tie to is available:<ref name=GrogTwist>{{cite web|title=Constrictor Knot: Twisting Method|url=http://www.animatedknots.com/constrictor/index.php|access-date=4 May 2014}}</ref>

File:SikistirmaBagi 2.JPG| 2 : thumbs with the rope are rotated 90 degrees to cross each other forming loops 
File:SikistirmaBagi 3.JPG| 3 : The resulting two loops are folded around the crossing point and held together.
File:SikistirmaBagi 4.JPG| 4 : the resulting two loops are slipped together over the end

If one or both of the ends are folded in between the two loops and lead in the opposite direction, the knot becomes slipped.

===Folding method=== 
Using one hand when the end of the object to tie to is available:<ref>{{cite web|title=Constrictor Knot: Folding Method|url=http://www.animatedknots.com/constrictorfold/|access-date=4 May 2014}}</ref>

If the rope is to be stretched in tension, the grabbing at stage 2 may first tighten the top side rope, the bottom side rope may be pulled to tighten the knot itself, and the bottom rope side may be tightened by the knot at the next pole. If one or both of the ends are folded and led in the opposite direction before the last loop is folded over the objects end, the knot becomes slipped and therefore easier to untie: It also makes it possible to stretch either side rope tight by pulling at the slip loops.
