The problem of the metal of the cane tip wearing thru and
the tip coming apart is the only failure I have noticed in the
tip itself. As I said earlier, however, in fiberglass canes,
the screw upon which the tip fits tends to come unglued/unscrewed.
The only solution is to epoxy it back in when possible. In
my last fiberglass cane (which is five years old), this was
not possible as the screw came partway out and I can neither
pull it all the way out nor push it back in where it's supposed
to lodge. But back to the cane tip. I wonder if John's solution
of thickening the metal skirt might not increase the weight of
the cane sufficiently to alter the center of mass of cane/tip
to a noticeable degree? Experiments along this line might be
