Sword fingers (also known as Sword Formula) is a traditional hand gesture originating from Taoist rituals and Chinese martial arts, representing the shape of holding a sword. Its core movement is: the index and middle fingers are extended and held together, while the remaining fingers (ring finger and little finger) are curled inward toward the palm, with the thumb gently pressing on the knuckles of the curled ring and little fingers; it can also be simplified to just extending the index and middle fingers together, with the other fingers naturally folded in, to mimic the shape of a sword blade. It is often used to point directions, show momentum (e.g., "sword fingers pointing to the sky"), or perform rituals as if wielding a sword.
Classic example: In the game—Honkai: Star Rail, dan_heng_(imbibitor_lunae)_(honkai:_star_rail) uses the standard sword fingers gesture when casting skills.
