Hame headed canes do not work well for orthopedics and the WILL be conviscated on an aircraft and in any area like a courthouse where you go through a metal detector. If you want invisible, get the heaviest all wood (no metal at all!) crook (aka tourist) handle cane you can get. I have advocated the Enesco elephant cane, at least until I can find one heavier. They are also easier to carry than ball headed canes and are more useful for self defense than any other form as they can be used for trip and control moves.
