I've been gutting deer for about ten years and I still manage to cut into/knick the stomach more often than I would like. The last deer I shot I put his butt on a down hill slope so the guts would move away from the sternum and tried to cut shallow under the sternum and still knicked the guts. I cut and pull the skin back so I have a good cutting area. Once I get the initial cut I'm good.....i use a zipper blade. Is there an easy way/trick to prevent cutting into the stomach on the initial cut?
