If I am using a utility knife with a retractable blade, I put the blade out full length and try to cut to full depth.
Good luck,
Richard
I saw a video with a blade 2 or 3" long, is that what you mean by utility knife? The only knives I saw in Home Depot were either snap off blades, and I'm not sure they have rigidity, box cutters or something long enough to gut a deer.
