Want some sage advice? The answer is no he couldn't differentiate. The pointed edge vs. smooth theory makes sense to a sighted person because we can relate the pointed edges to the smoothness because our sense of feel correlates to the vision of shape and it's relationship to space. We can see and feel that it is different. A blind person can only relate to touch with no comprehension to size and it's relational difference. The feel of round and smooth is a theory decribed to the touch but not registered in the brain beyond theory.
