List of nodes

The half knot is a tying knot that is used to tie up packages, shoe bows and the like. Well-known knots - where the half knot is used - are, for example, the square knot and the shoe knot . In the vast majority of cases, the half knot does not appear as an independent knot.

Knot

The half knot is tied with two rope ends. It can only have two different orientations. When knotting, you either place the left end of the rope over the right or the right end of the rope over the left. The statement left over right is not absolute, it depends on the viewing direction. Therefore, you can tie the knot in four different ways, but ultimately you only get two different knot turns. (see also lay direction ).

  • Image 1: rope ends at the top.
    Left over right half knot.

  • Photo 2: rope ends at the top.
    Right over left half knot.

  • Photo 3: rope ends below.
    Right over left half knot.
    Image 3 is essentially the mirrored image 2

  • Photo 4: rope ends below.
    Left over right half knot.
    Picture 4 is basically the mirrored picture 1.

Two half knots

Depending on the orientation with which two half knots are tied, there are different knots that have completely different functions:

  • Square knot , also reef knot
    Here the two half knots have different orientations - first placed left over right and then right over left. The ends of the rope are parallel.

  • Old
    women knot If you tie two half knots with the same orientation - here twice left over right - an old women knot is created. The ends of the rope come out at an angle.


  • Thief's     knot If you do not tie a half knot because you do not tie both ends of the rope around each other, the ends of the rope slip out under load and the knot loosens by itself. The ends of the rope are diagonally opposite.

Further application examples

Demarcation

The half knot is often confused with the overhand knot and the half knot . These three nodes are very similar in structure, but have clearly different uses. See also the section: Delimitation of the overhand knot!

Direction of impact

In technical terms, one can find two lay directions - independent of the viewing direction - at the half knot , one with an “ S ” or one with a “ Z ” lay direction.

You can see in the gallery below that there are only two differently tied knots. Fig. 1 shows the same lay direction as Fig. 2 and Fig. 3 shows the same lay direction as Fig. 4. The other is only laid with the other end of the rope (red or yellow). The direction of impact is the same.

  • Image 1 rotated by 90 ° in UZS.
    An " S " tied half knot (the rope with the red end shows the letter S ).

  • Image 2 rotated by 90 ° in UZS.
    A “ Z ” tied half knot (the rope with the yellow end shows the letter Z ).

  • Fig. 3 rotated by 90 ° in UZS.
    An " S " tied half knot (the rope with the yellow end shows the letter S ).

  • Fig. 4 rotated by 90 ° in UZS.
    A " Z " tied half knot (the rope with the red end shows the letter Z ).
