Use the knife to cut off the top and bottom as shown in the photo. Clean the blade of the knife after each cut with a damp towel. Dry it out thoroughly. If the body is soft/squishy, not holding the shape and you don't get sharp edges when cutting, add more CMC to the paste and remake the body. The body needs to be firm so that it can hold the heavy head. You can also leave the paste to dry for a few minutes before cutting. Put the body aside to dry.
