Cold Steel African Walking Stick is the one I own. Very good, well made. I carry it because in my area there are a lot of Foxes and dogs that people let go so since I walk with my dog I do not want a dog from the street going at my dog. The walking stick is very strong.

There are many places that sell it online.
