Flip-Flop winch

This looks too simple, and might easily become dangerous. But it might get you out of a stuck, or be able to move something heavy.

New skill in the brain bank, thank you!! Now I want to try it...

I learned that in prison! Just kidding, that's pretty ingenious however, agreed, don't know how much I would trust the thing not to shatter in to a million splinters and take a eye out.!

Interesting technique if you are solo and don't have a winch, come-along, or hi-lift with you... Great idea, but I would hope to never have to use the method!

Hmm interesting. In a pinch sure, but as the risk of shater or rope failure is so very high I think this a good emergency skill.
