A self righting walking cane device which comprises a lightweight hand grip handle, a lightweight shaft device and a bottom weighted base device to facilitate the righting action of the cane device. The base device includes a plurality of frame devices and faceted shell sections which are attached about the bottom portion of the shaft device. The frame devices or shell have a unique configuration which together with the weight device positioned about the bottom portion of shaft device which together with unique shaft configuration provide a unique self righting walking cane.
