In this article, we will explore the Definition and Impact: Knot efficiency refers to the percentage of original rope strength retained when a specific knot is tied. It has to do with how sharply the rope is bent. Learn what you can expect from ropes which have been spliced, knotted or hitched when it comes to rope efficiencies and This exploration delves into the art and science of rope knotting, aiming to reveal the critical factors that govern how knots function and retain rope strength.
