😱 What really happens when a climbing rope runs over a sharp edge during a real fall? In this special guest episode, we put our lab-designed cut resistance test to the ultimate challenge — comparing how ropes perform in real dynamic fall scenarios over stone edges.

And joining us is none other than Tommy Caldwell, one of the best big wall climbers in the world, to help us understand what really matters when the stakes are high.

In the lab, we’ve engineered a precise way to measure a rope’s cut resistance — but can those numbers actually predict what happens on the wall? Together with Tommy, we explore how factors like belaying technique, rope handling, and smart edge management can make the difference between safety and disaster.

Watch the full experiment, the drops, and Tommy’s insights — and learn what you can do to keep your rope (and yourself) safe.
