You can do the whole animal but they are particularly good for opening the stomach so that that everything is contained as to not contaminate the meat, The are excellent for skinning, it just knife skills and knowing how to use them.I have made a few of those field dressing tools (the green handle set) but for some reason I cannot get the rednecks here to understand what it is used for. They keep trying to skin the whole animal with the one tool meant for opening the cavity...Great work
