I wonder if Un Lun Dun by China Miéville counts? In that the protagonist does get a magic weapon eventually, but it's the type of magic weapon that works for anyone who picks it up and has the imagination to work out how it can be incredibly powerful when used with lateral thinking, rather than one that's powered by or otherwise requires the owner's SPESHULNESS. And the general point of the novel is violently anti-Chosen One.
