I use a Swiss Army knife that has a lock blade and a gut blade. It works really good on dressing out a deer. I' ve been using the same knife for over 10 years and the blade still will hold an edge long enough to dress out several deer! Everyone' s first impression is to laugh at the knife, but by the time I get through skinning up, they all want to know where they can get one!!! It' s a great knife!
Here is a link to where you can get one, and I think they have free shipping!
