A left-handed sheet bend creates a much weaker connection, especially under moderate loads.

    That

    is one mother fucking cursed connector

    it’s brilliant because it’s so hazardous yet still creates a contact between two double core wires.

    I want to see IRL photo of this connection.

    The knot also needs to be adapted for common two-core electrical appliance cable, if you remove a piece of the insulation on one side and with an offset on the other side, the cable needs to be twisted mid-knot to match the correct wire.

    WTF? the sheet bend is close to a square knot which is much more secure. Or a thieves’ knot if you’re looking for something that slips apart after limited tension.

      A sheet bend is more secure for cords of two different types/diameters. A square knot is for cords of the same diameter.
