I carry one in my truck. I turned it myself from Osage Orange.
Even though, at age 73, I don't need a cane I have made myself a couple. One has a 1" hickory shaft and an antique brass horse hame tip. The tip is quite heavy and would dent a bowling ball. I figure a 70+ year old man using a cane would not be questioned. Actually, I'm pretty healthy and agile. Someone mess with me or family they will get a rude awakening just before I put them to sleep.
