Ollivander has always led us to believe that the wand choose the wizard.
But Eddie Redmayne revealed he was allowed to design his wand in the upcoming Fantastic Beasts And Where To Find Them film - and a LOT of thought went into it.
Eddie plays Newt Scamander, a magizoologist who accidentally lets loose a host of magical creatures on New York City, so naturally it would be a wand for animal lovers.
He told Entertainment Weekly: "I sort of assumed that I would have a wand sort of plopped in my hand.
"But the reality is that these amazing props designers come, and then you have really a quite intricate discussion with (director) David Yates about what qualities Newt has.
"He's not a showy guy, Newt, so I wanted it be to quite simple. So we decided to have the wand be made out of ashwood, and it has quite a few scratches and sort of burn marks -- so that you could get the sense that he's been travelling the world with it, and it's got quite a history to it."
He continued: "But for the handle, they were sort of talking about whether it should be horn or leather, and I didn't like the idea of like animal products being used, given that he's a zoologist. So in the end, they came up with this idea of sand shell... and it has a slightly mother-of-pearly feel.
"So we had all these discussions and went back and forth with designs, and when the thing arrived I was pretty excited."
Eddie said he was like a schoolboy when he first got to hold the sacred stick in his hand.
"My inner nine-year-old was having a disco, and then I was actually presented with it!" he said.
Fantastic Beasts And Where To Find Them is in cinemas November 18.
