My 6 year old daughter was playing with ropes today and tied a knot of her own creation. I tried to demonstrate to her the importance of learning to tie good knots that don't slip, but when I went to yank on her knot, it didn't slip at all. Upon further inspection I concluded that it appears to be a rather sound friction knot. The more force you put on the rope, the tighter the choke on the tail end. After looking at it long enough I started to wonder if I've perhaps seen this knot before in ABOK.
Does anyone recognize this as an established knot?
