The Stone hitch (aka Stone knot or Stein knot)

[@thelateknights]

1:30 is the tying, just in case you wanted to watch it over and over again

[@akaTheDevil]

Would tie it in to both also work?

[@johngo6283]

Yes, it would.

[@emiliepeeters4809]

Is it somehow possible to back up the anchor with the rope or is it overkill?

[@johngo6283]

There’s no need to back up the anchor with the rope. It’s set up for a normal rappel.
