I came up with this variation of the flat overhand knot (also known as the Euro Death Knot) for pulling ropes on a rappel. I've never been comfortable using the Euro Death Knot (EDK), but it's hard to deny the virtues of the EDK for retrieving ropes. I set out to try and come up with a knot that had less of a tendency to roll than the EDK and eventually came up with this:
It's a flat overhand with one of the strands tied in a double overhand, which, if anything, makes the knot feel a lot more secure.
What I want to know is if this is an original knot, or if it's already been discovered, has a name, and most importantly: whether or not it's being used for rappels.
I came up with a different knot while experimenting, but found out online that it had already been invented and named "knot number 1452" back in the 1940s. This knot however, I can't find any evidence of it being used before.
Does this knot have a name? Or have I come up with something new?
