ABSTRACT:
The present invention comprises a cane assembly for the visually handicapped, to permit maximum tactile and auditory information between terrain touched by said cane assembly and a user thereof. The cane assembly includes a tapered metal cane shaft having an upper or proximalmost end and a lower or distalmost end. A metal handle with a finger groove is secured to the upper end of the shaft and a solid elliptically shaped plastic tip is secured to the lowermost tip of the shaft. The elliptically shaped solid attachable tip permits the cane assembly to provide superior touch and sound from all terrain encountered, without the likelihood of snagging on a crack or the like.
