That’s because the knot is not loaded….should the rope spin and then load that knot the system is no longer 100% it is considered 97%. Another method is to simply bight or choke the working end around the standing end and wrap the the anchor once in the opposite direction then tie the overhand or clip in the tail.
The intent of the overhand knot is to eliminate or minimize the potential of the knot spinning around a round smooth object. It also eliminates the potential of loading the tail of the rope.
@@systemicXMR It would….if for some reason the rope slips and the knot becomes loaded. The reduction in strength is reported as 3%, so where a tensionless hitch is 100% a high strength tie off (if loaded) becomes 97%
What is the benefit or difference in potentially loading the overhand knot vs the lower potential (due to one more wrap of friction) of loading the figure 8 at the end of the rope?
Seems like instead of figure8-on-a-bite and clip to the load line one could just tie a follow-through-figure8 to the load line directly. Removes a link in the system, albeit makes setup/take-down a bit slower.
Yep, very simple, doesn't take that much longer. There isn't much sliding movement at all to generate friction, so I don't see a problem with 'rope on rope' in this application

Our department makes the figure 8 on the bight first before the wraps. The last thing connected would be the caribiner. Good video doh
Seems odd to say that you retain 100% of the mbs of the rope because there is no knot, then say to tie an overhand knot.

What does the over-hand add? Seems you could just dress/set with the fig-8 connect.

@@CMCPro Thank you.
So that overhand would or wouldn’t account for a loss in breaking strength if it spun?

Good video. Lose the music and replace with narration in the future. Music adds nothing because it isn't information.

Exactly what I was about to say.
You do not want a rope on rope connection as this can cause heat to build and cause a failure.

Lose the stupid music and mix in a Voice over. Couldn’t watch the whole thing.
