A cane for use by a visually handicapped person which has a tip at its bottom end which has a relatively broad outwardly facing convex contact surface. When slid along the ground as the person walks, the cane tip, which is preferably a hollow shell, provides auditory and kinesthetic clues about the environment and any impediments in the path of the user, yet cannot get caught, stuck or hung up on any obstacles.
