I always use a box cutter when one is at hand for cutting cardboard. It is abrasive, and some people actually use cardboard as a strop when a real strop is not available.
It is easier to reverse or change a single-edge razor blade than sharpen a good knife, and the razor blade generally lasts for some time.
I just helped with a move, and the box cutter got more use than my pocket knives, though there were times when I reached for them.
