I have not found any cane/walker products. There are walkers that can
be turned into chairs, but I think it would be difficult to turn
something as complex and bulky as a walker into a cane.

I HAVE BEEN ON A PLANE AND SAW BOTH PRODUCTS..THEY EXIST

Is this anything near what you're interested in finding for a
cane/walker?  I realize this **isn't titanium**, but is it close to
what you saw on a plane?

the cane walker that I saw was one that looked just like a cane and
when you clicked it open it bacame a 3 point walker, very compact,
light and sturdy....the woman who had it said she got it out of a
catalogue and it was costly  but worth it.

The wheelchair I saw on a flight I recently took was narrow enought to
go down the asile of plane ,portable, sturdy and weighed about 10 to
12 lbs. The young man in this chair was a basketball player from UOFA
and he was tall and about 190lbs. He said that it was custom ordered
for him but it would be easy for me to find.???
