The Real Reason Behind Voldemort's Wand Design In Harry Potter

According to a comment from user PristineAnimator683, the reason for the hook element at the grip of Voldemort's wand had something to do with Ralph Fiennes, as he requested the wand to be designed this way. According to the user, the actor wanted to move more "fluidly and snake-like" without dropping his wand in the process. Although Fiennes was never quoted saying that it helped him be more "fluid and snake-like," in a video interview with GQ, the actor did confirm that he requested that the hook be added, but more so for it to not fall off as he felt the wand should be an extension of his hand. Fiennes noted that he appreciated its lightness, and it helped throughout the production of the films.

Other users on the Reddit thread soon began suggesting possible and plausible reasons why a dark wizard might have a hook on a wand in the Wizarding World to support the actor's choice, with many suggesting that it could be prevention to the disarmament and the Expelliarmus spells. User quirx90 joked that they always wondered why wizards never put a Wii strap on their wand to keep it from flying away, but user Ritz527 was quick to say that with the way magic works in the Wizarding World, the strap would probably break anyways. User barbeque_invader supported that claim, as they mentioned the spell itself is literally to "disarm" when cast, so "it might make the strap not work as though you forgot to even use it."
