Go to:

 Split one or more vertices so that each face that shared the vertex
 acquires its own copy of the vertex. This operation will affect all the
 edges and faces that shared the vertex. Also, this operation may create
 non-manifold geometry as a part of this operation. You can use
 Polygons->Cleanup afterwards to to clean up any non-manifold geometry.
