Sixth-Seventh Book Answer:
He uses Harry's own wand. Not the Holly and Phoenix feather, but the Elder Wand.
In the sixth book, The Half-Blood Prince, Harry watches Draco Malfoy disarm Albus Dumbledore, who was the Master of the wand. The wand goes to it's new master by right of conquest.
When Harry Potter, Hermione Granger, and Ron Weasley are captured in the seventh book, the Deathly Hallows, Harry disarms Draco, who is not in possession of the Elder wand, but that still makes Harry the wands Master.
Then, when harry faces down Voldermort, he finds Voldermort in possession of the wand. He taunts him, and disarms him, reclaiming his wand, but vowing to try and extinguish its power by dieing a natural death.
Fourth Book Answer
Voldermort uses his own wand, yew and phoenix feather. Harry and Voldermorts phoenix feather came from the same phoenix, Fawkes, Dumbledores familiar. The wands connect in a cage of golden light and show a ghostly image of everyone killed using Voldermorts wand. They fly towards Voldermort, giving Harry the time he needs to escape.
This takes place in the Goblet of Fire, in the graveyard of Little Hangleton, where Voldermorts father was buried, and where he was resurrected.
In order to avoid the problem of the twin core in Harry and Voldemort's wands, Voldemort takes Lucius Malfoy's wand to attack Harry as he leaves Privet Drive in Harry Potter and the Deathly Hallows. However, this tactic is ineffective.
Lucius Malfoy's, if you mean the movie, since that is only the first part (THUS FAR). Since his own wand doesn't work against Harry, he takes Lucius' and then later steals the Elder Wand from Dumbledore to use.
As Lord Voldermort is aware of the connection between the two Phoenix wands, he borrows Lucius Malfoy's wand for the chase in Private Drive. Unfortunately for Lucius, though, a spell Harry never meant to cast smashes the wand into hundreds of pieces.
the Elder wand from The Tale of the Three Brothers- Albus Dumbledore's wand.
He uses Lucius Malfoy's wand as Harry leaves.
Lucius Malfoy.
Voldemort used Lucius' wand while chasing Harry on his 17th birthday.
Yes he does posses it but never is the owner of it. It is confusing but I will explain from when Dumbledore has it. OK Dumbledore has the wand and is it's master. Draco disarms him and because of it unknowingly becomes the owner of the wand. Voldemort steals the wand from Dumbledore's grave but because he is not the true owner it does not work for him. Voldemort believes because Snape killed Dumbledore he is the owner of the wand so kills Snape. Harry wrestles Draco's wand from him and physically overpowers him becoming the new owner of the Elder wand (due to Draco's defeat) Then Harry and Voldemort face off, Voldemort with the Elder wand that Harry masters so Harry wins. So Voldemort Physically has the wand but never masters it so it works as normally as any other wand for him.
Well, it is a big story. Only if you have read all of the books you will understand, but i will give you an answer. You-Know-Who killed himself with the wand he was using;the Elder Wand. The Elder Wand is the strongest wand in the world. Whoever wins the owner takes it and it only works for him. So Voldemort went and stole it from Dumbledoor΄s dead body because Dumbledoor was the last who had it. But it wasn΄t really Dumbledoor΄s wand because Malfoy won Dumbledoor on the 6th book. So it didn΄t work for Voldemort wen he used it against Harry because Harry won Malfoy in a battle. So Harry became the owner of the strong wand. And wen Voldemort used the Auanda Kendabra , the killing curse,with Harry΄s wand against Harry it went back to Voldemort because the Elder Wand couldn't kill its owner. And that's how Voldemort was killed.I don΄t know if you understand it because its complicated. You have to read the book though, its more nice like that and you will understand more things. They way I think it happend ( I have read the books) was that Harry did have control over the elder wand but it wasn't that reason that voldemort was killed. Harry and Dumbledore had destroyed all of voldemorts horcruxes(Including Harry) and then when Voldemort used the "Avada Kadavra" on Harry, Harry backfired it by using Expeliarmus(Harry's signauture attack) just like in the second game. Harry ended up being the master of death. Invincible!
The reader doesn't know.
Harry's wand is holly wood and has a phoenix feather core. The feather comes from Fawkes, Dumbledore's pet. The core of Voldemort's wand is also one of Fawkes' feathers.
he uses lucius malfoy's wand
Lucius Malfoy's.
Harry Potter's wand and Voldemort's wand

Voldemort used Lucius' wand while chasing Harry on his 17th birthday.
Harry's wand in the night Voldemort regained his body the wand took a bit of Voldemort's deadly skill and used it against him the night he chased Harry across five counties.
Voldemort steals it from Dumbledore's grave, but it is rightfully Draco Malfoys, then Harry disarms Draco, so the wand is Harry's, but Voldemort still has it. Then when Harry defeats him, Harry takes the wand, but instead of keeping it, uses it to mend his Pheonix wand.
He dueled with Lord Voldemort and Harry was somehow the rightful owner of the wand, so the wand flew into Harry's hand, leaving Voldemort with no weapon and to his death.
Because Harry is the true master of the Elder Wand. Or because Voldemort's course didn't actually hit him, it fall back on Voldemort. I think this was because Voldemort couldn't kill Harry using a wand that he hadn't rightfully won? Or the wand didn't want to kill it's true master.
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.
It was too late. Voldemort already knew where the Elder Wand was and was going to get it.
Well the Elder wand has a long backstory but basically Dumbledore starts off with it in the book. Then when Draco disarms Dumbledore he becomes it's master unknowingly. Then Harry over powers Draco becoming the new owner. Voldemort kills Snape who killed Dumbledore so he BELIEVES that he is the true master of the Elder Wand. Then Harry and Voldemort face off Harry being the master of the Elder Wand. Voldemort's wand (The Elder wand) Then flies to it's true owner leaving Voldemort defenceless. Hope it helps!
