Bachmann knot

Nudo BachmannBachmann knot was invented by Franz Bachmann. A knot is dynamic, ie it takes around a larger diameter rope. The Bachmann knot requires the use of a carabiner. No matter if the carabiner is locked or not.

The important thing is that the hook section is round. Although usually used a rope, we can do with a flat ribbon tubular and with a minimum of 4 wraps around the body of the carabiner.
