According to Ollivander what is so curious about Harry Potter's wand?

Answer 1

That the wand that chose him had a phoenix feather in it, and the phoenix only ever gave one other feather which was to Voldemorts wand, and Voldemort was the one who could not successfully kill Harry, which was the only case of that ever to happen.

Answer 2

Ollivander supplied Harry Potter with a wand, and as he did so, he told Harry a few facts about wands. He explained that a wand has a core, in Harry's case a phoenix feather. He told Harry that the body of the wand is made from a choice of different woods with different magical properties.

Answer 3

Because the wand, the twin of Voldemort's, chose Harry. The fact that it is the twin of Voldemort's is curious, because it was the wand used to try an kill Harry.

Answer 4

The fact that it was a "sister wand" (used another feather from the same phoenix) to the one that had attacked Harry Potter, causing his scar. In other words, Voldemort's wand.

Answer 5

Harry's wand is the twin to Lord Voldemort's wand.

Answer 6

The unusual thing about Harry Potter's wand - one that plays an important role in the story plot - is its connection with the wand used by Lord Voldemort.
