I have deboned my 3 whitetail does that I have gotten using the hook and the video above as a guide. It worked so well that I bought this meat grinder. The butcher where I used to take my deer now charges 75$ per deer. He does a great job, but the money I saved paid for the grinder. Now I'm going to get a semi-stiff 6" boning knife to make it a little easier.

PS: A buddy of mine said that the one he bought looks like a toy compared to this one.
