Many knots are not suitable for the risks involved in climbing. Seek professional instruction. Many of these knots have histories of use tracing back hundreds of years. However, many critical factors in their use today cannot be controlled, including: the appropriateness of knots used in particular applications, the age, size, and condition of ropes (knots weaken the rated breaking strength of rope anywhere from 50% to as much as 80%, even more in the case of old and worn rope); and the accuracy with which these descriptions have been followed.
