Single vs double fishermans?

[802climber]

I was wondering if there's an advantage to using a double fishermans for eye to eyes, lanyards, etc. I have always used a single fishermans to terminate my climb line if it doesn't have a spliced eye.

Either I don't understand or we need to talk the same language.

Anchor hitch is what I have always used.

Which may be yet another name for the same knot the OP is asking about.

Anchor hitch. They never walk on you either.

All climb lines and lanyards spliced here, but if I were to need to knot, it would be first choice anchor, second, scaffold.

Wow. When I said single fishermans, it looks like I am actually referring to a double overhand knot... Glad I asked.

What are acceptable termination knots for an e2e split tail then? Only double fishermans?

Since it would life support... yes not a single. Double fishermans

Again, knowing the terminology is helpful when it comes to knots. One knot used to terminate E2E cords is called a scaffold knot, which is one half of the double fisherman's knot. A scaffold knot is fine on most kinds of cordage, climbing lines for sure.

Some hitch cords, like Ocean Vectran or Armor Prus, are made with a core of high modulus (low stretch) fibers. For ropes with this kind of core, it is recommended that you add another turn, making making 1/2 of a triple fishermans knot. The core on these ropes can be pulled thru a scaffold knot under extreme loads, but not with the additional wrap.

This really shouldn't matter for E2E cords because you aren't applying crazy load to the knot, but I on those specific ropes I tie the third wrap for extra security/ peace of mind.

Thanks! Seems I just can't get my terminology straight.

To make things a little clearer, I think ruel means half of a double fisherman's bend.
