(Strength: 5/Security: 5/Stability: 5/Difficulty: 4) See below for what these ratings mean.



Each knot will be assigned a rating from 1-5 (1 representing the lowest score) based on the following four properties:

Strength – All knots will weaken the strength of  a rope, however, there are knots that are stronger than others. The scale here will reflect how strong the rope remains with the specified knot.

Security – The security scale refers to how well the knot will stay tied, and resist coming loose under a normal load.

Stability – Stability refers to how easily the knot will come untied under an abnormal load (i.e. the knot being pulled in a direction it was not intended to) A lower score here represents instability.

Difficulty – The lower the number, the easier a knot is to tie.

    Thanks for the video. I have a couple of questions:

    Why do you use a “triple” fisherman’s bend?

    Why do you feel that the bight needs to be protected from the attachment point on the carabiner with the tubular webbing?

    Unloaded carabiners (like those used in fall protection setups) are at
    risk of cross-loading or gate-loading when subject to a fall. Have you considered using a carabiner designed to reduce instances of cross-loading for the harness attachment?

    Thanks again! Don’t forget to dress and set those knots before you live load them.

    The more common not as tactical place these could be helpful involves high ropes courses for scouting.

    Mallion for the harness attachment eliminates the cross-loading.
