Can two wands be the same?
No, because Ollivander (or Gregovitch, 7th book.) makes them,
and gets unicorn hair from a different unicorn each time. Also,
because if they were the same, they would have to act the same, and
as you know, no person is exactly the same, so for one, it would be
perfect, but for the other, not so good. So, no, there is no wand
that is the same.
