Oh sweet lord, Shane has no idea what he's talking about. Don't learn a figure eight knot, it's useless on set. Use a bowline for what he's doing. He clearly has no idea what a sheepshank is for (hint: if you don't already know what it's for, you don't need one), but what he's done with it is create an overly-complicated, modified trucker's hitch that has the added benefit of being INCREDIBLY dangerous. Seriously, it would slip apart if you looked at it wrong. The added "torque" he describes simply doesn't exist. I'm actually shocked by what he did, did he just make that up? Who taught him that? Someone who wants him dead, perhaps. Learn the bowline, clove hitch, trucker's hitch, rolling hitch, sheet bend, round turn and two half-hitches, and square knot.
