From what I gather he just knocks it away, then lifts it and throws it at Thor during their battle...
Thor of course will be devastated at this turn of events and slither off from the battle with no clear winner being seen because surely we cannot show Thor defeating Vision who later on in the movie will ultimately kill Ultron...That would make no sense it would seem...
Actually the movie ends with a new party scene in which Thor and vision play spin the bottle with his now useless hammer while the others take jabs at how Vision is now worthy to rule Asgard..
Thor of course reluctantly agrees and goes to Asgard to make way for the new King...
Its no wonder they moved Thor 3 to a later date, with so many liberties being taken with this Asgardian the writers are having to go back to the drawing board to make any sense of it....
