I have several canes (for mobility reasons) and hiking staffs (again, for mobility reasons), a couple of canes I have are made of hickory, have a shepherds hook on the end and are engraves with handholds, they are defense tools as well as mobility tools, the others are made of some other type of hardwoods and they are strictly for walking, one of my canes and two of my hiking staffs (both favorites) are made of fire hardened Bamboo, they are light but extremely strong.
While I'm hiking or generally woods bumming I always rely on a hiking staff, they are not just for stability, but with a well made staff you can fend off most small and medium sized animals (think rabid raccoon, skunk, or even a timber rattler when surprised by either, it's good for moving brush out of your way, and in some instances can extend your reach, such as when trying to fill your bushpot with water, from a stream or shore line and don't want to get your feet wet, and of course they are good for holding up a tarp you're using for a temporary shelter.
