I have eaten a banana with a knife and fork from a plate. I was at a business breakfast and the South African gent across from me was fascinated! Cut the ends of, split the skin, push it back and eat in slices. Really easy. Fairly sure I saw a cartoon showing me how to do it once.
Now I open from the bottom, because that is the most efficient way. If other primates do it, I trust they know their bananas.
