Im serious. I think I COULD tell the difference, especially if the knives were the exact same pattern, same handle material, everything the same. If they were different knives it would be very difficult.

Without the benefit of sight, I would rely on comparing how they work first. I'm not sure if you could FEEL a difference in finish between the two. That would be dang near impossible. But, I'm guessing and don't think that I will ever see the planets aligned in such a way as to ever experience this test.
