Wolverine is a Marvel mutant best known for his retractable adamantium claws, and the metallic snikt as they extend has become one of his signature traits across comics, animated series and the live-action X-Men films. The sound works as audio shorthand for the character even without showing him, so fans and editors reuse the short clip in memes, fan edits and gaming videos. Its brevity and instantly recognisable metallic edge keep it useful decades after Wolverine first became a pop-culture favourite.
