Vin's Obsidian Daggers

Vin's Obsidian Daggers first appear in The Well of Ascension as a pair of non-ferrous, glassy blades that grant her immunity to steel and iron Allomancy, allowing her to strike without fear of being pushed or pulled. Across the series, these daggers evolve from a simple tactical advantage into a signature weapon that embodies Vin's growing independence from traditional Allomantic combat, culminating in their use against both mortal and divine foes. Their significance peaks when they become the instrument of Vin's final confrontation, transforming from mere tools into symbols of her defiance against the Lord Ruler's legacy and the forces that seek to control her destiny.
