Shichi's katana

Shichi's katana was the holy magical katana of Shichi No Ken, a paladin of Amaterasu, in the mid–14 century DR.

Powers
It was a +3 katana that could detect evil at will, remove a curse thrice a day, cure serious wounds on another (not the wielder) once day, and banish extraplanar beings with but a touch once every seven days. Moreover, it was a holy sword: in the hands of a paladin and unsheathed, it emanated a "circle of power" wide that dispelled all lesser hostile magic.

History
Along with a daikyu, the sword was enchanted and gifted to Shichi by the Grand Master of Flowers when she departed the Seven Roses Monastery in Pe Nok to become a "walking initiate".
