Names and history
This knot is used by French and Austrian speleologists and is becoming more and more popular in Germany and Switzerland. In nautical science, two of these knots are used to connect equally strong ends as a double spar stitch . This is why cave explorers sometimes call it a spar stitch loop or demi pêcheur double .
application
The cave knot (also known as the spar stitch loop) is used to attach the static rope or dynamic rope to the snap hook . The hook is fixed in the knot in such a way that it does not move and can therefore be handled more easily. It is not used for roping up .
This can also be used to create quickdraws or short loops for self-belaying, called “lunge” in cave exploration. In France, such longs were examined for breaking load , impact force and knot strength . The cave knot has the lowest impact force values and is therefore best suited for self-belaying.
