This knot connects two fishing lines of different thicknesses. The knot is similar to the [Barrel Returnable (Bloody Returnable)](https://fishplanetapps.com/apps/fishing-knots/knot/knot-380). The difference is that the thick line does not twist around the thin line. The thin one is folded in half and twisted around the thick one. Thick fishing line is woven into the winding. After this, the [Barrel Returnable (Bloody Returnable)](https://fishplanetapps.com/apps/fishing-knots/knot/knot-380) is performed with the free (running) end of the thin fishing line, as usual.
