The prusik knot, which belongs to the category of "self-locking" knots together with the famous machard knot we have already talked about: • Lunghezza Cordino Machard
Today we see how to do it in a "classic" way by having a closed cord ring, which is also the easiest way.
1 - 0:01 min We take a loop of rope usually closed with a double English.
2 - 0:06 min We move the node to the base leaving two fingers of available space
3 - 0:12 min Pass around the rope and pass the entire double English through the closed cord several times.
4 - 0:20 min Take care not to overlap the coils.
5 - 0:36 min To lock the knot it is sufficient to pass one last time checking that the coils are close together and not overlapping
6 - 0:42 min The number of coils also depends on the size of the lanyard compared to the rope. The more similar are the diameters of the two strings,
the greater will be the number of coils needed to make the knot work correctly.
7 - 0:46 min The prusik knot is "bidirectional" and slides along the rope on which it is mounted, as long as it is not subjected to strong traction.
8 - 0:56 min The carabiner is applied under the double English knot.
For optimal functioning, the knot should be tied using a rope with a much smaller diameter
than that of the string on which it is performed.
Curiosity. The knot takes its name from its inventor Karl Prusik, an Austrian mountaineer.
