My family and I have done large cuts of meat from another grocery store and used a friends band saw, he got it for processing deer, to cut them into steaks almost no waste at all. Are you talking about de-boning the cuts? Realistically there really shouldn't be much waste at all.
The one I was looking at didn't have a bone in it. The couple of youtube videos I watched they were just using a chefs knife to cut the meat.
