Just set the normal binding to be per primitive/face and not per vertex if you want to have sharp edges and define face normals. Otherwise, if the corners/edges are to be smoothed, you use normal binding per vertex and calculate normal as an average of the face normals of the faces adjacent to the vertex. There is no need to duplicate any vertices - in fact, that would only give you artifacts.
