You should consult with your local Orientation and Mobility instructor. I can tell you the cane I use and why.
I use a 60 inch rigid graphite cane with a ceramic tip. It has a rubber handle and an elastic string that runs through it, that you can hook different tips to on the end.
60 inches - Technically the cane measurement based on how I walk and how tall I am would be 50 inches but I have an extra 10 inches because of the way I hold it. I have a lot of wrist pain and can't handle the weight of holding it the classic way so I lean it against my forearm instead.
Rigid - I like rigid because it gives me more direct tactile information and I hate having to deal with folding my cane every time I sit down. I usually end up treating a folded cane like a rigid one, lol.
Graphite - This is the lightest (but most expensive) material on the market. It is really very light. My cane is much lighter than the classic Ambutech aluminum folding cane. Needless to say, this makes swinging it a lot easier on my wrist and arm, and also makes coordinating caning with one hand and signing with the other a lot easier.
Ceramic tip - I walk a lot and the ceramic tip lasts me the longest. (About 6 months compared with a typical Ambutech rubber marshmallow which lasts me about 2 weeks.) It's also designed to be dragged lightly which is perfect for me cause I can't hear the tap anyway and I like the extra tactile information. Dragging it lightly also makes it a lot easier on my wrist.
I always use it outside the house. The only time I don't use it is inside my own house and when I am tactiling with someone and holding a drink at the same time.
I have a folding cane as a backup for situations where spacing is tight. The 60 inch cane fits easily inside cars and even airplane crafts, though. If your cane is on the longer side you just have to make sure to be aware of both ends when getting in/out of a car or other tight spaces.
Hope that helps you with the thinking that goes into deciding the right cane for you. Good luck.
