The Pointing Cane belongs to the Long Cane category, designed primarily as a mobility tool used to feel for obstacles. It is an extension of the user's hand/finger, so rather than having a round nylon tip, how about a 'pointing finger'? Grip handle is angled to relief stress from the hand when holding the cane. It does not matter if the idea is adapted to a collapsible or fixed cane, because the improvements are only done on the ends of the cane.
