What ist a perfect knot?

A good knot for practical use is characterized by the fact that it can be easily tied, held reliably and can also be easily detached. The properties of tauders and cords are crucial when choosing the right knot: especially the surface smoothness and the flexibility of the material are important for the selection of the right knot. A knot can be perfect for a rope of natural fiber, but it is completely unsuitable for a monofilament fishing line.
