rethreaded bowline (sport climbing tie-in knot)

[@hotharvey2]

Awesome, easy to tie (once I had slowed down the video 0.25 and watched multiple times...)
Easy to untie and super safe.
I add a stopper knot just for peace of mind :)

Doe it need a stopper knot?

[@jodelboy]

this version doesn't need a stopper-knot because the 2nd pass through the harness IS the stopper-knot.

Excellent
