I decided to run a search through the sub to see if this had been mentioned and it seems as if it hasn't. The National Federation of the Blind has a program where they offer fixed white canes free of charge to blind and visually impaired individuals. Of course you should always seek professional training on how to properly navigate using a white cane, but if you have been interested in finding out if one can benefit you this could be a good first step. Also, just as a matter of preference, many people (myself included) find that folding canes are much more convenient than fixed canes. These are free though so it could be a good first step.

I got my free cane a few months ago, and it is handy for certain things I do around the house, but I don't take it out and about with me due to it being a rigid came. It also has a metal tip rather than a rolling tip which doesn't work as well for people who have Learned the sweeping technique. It's built out of fiberglass and is extremely light compared to my folding revolution cane, but also feels like it will shatter if you hit something hard enough, plus it is totally white as opposed to a white cane with a red lower section. My O&M instructor says that it's really good for people who are advanced travelers.
