Due to circumstances, some of which were beyond my control, but most of which are due to becoming to soon old and too late smart, I have had to use a cane off and on for about ten years. I have two or three, made of sturdy bamboo and hickory and one that's some kind of metal. Have used the hickory and the bamboo on some dogs that tried to be much to friendly while my wife and I were out walking. When those dogs rush out now I just lift the cane and they hit the back yard where they live!
Neat thing is that I am old enough that no one would suspect I have a cane for anything but it's usual purpose. I can tell you that a good stick can deal amazingly serious damage, and it gives you additional reach that really comes in handy. You gotta be willing to use it without hesitation and with all your power and might, but intelligently in the process. Poke someone in the eye with the tip and see what happens! Leaves time for a good follow up! They say violence is not the answer, but when there is no other choice, violence is the only answer ... especially if it is sudden and fierce! In two hands, it makes a better block for a blow or a knife than an arm does, and then it can be transitioned quickly for an offensive use.
I don't carry it always these days because it requires a free hand, but truth to tell, I feel kind of naked without it. It's a great comfort, plus I can lean on it when I'm waiting and on my feet. I learned to carry my EDC on my left side while using the cane so I didn't have to switch hands with the cane or drop it to draw. Not a hard transition to make and I'm better off for it.
A determined person, young or old, is a formidible opponent. But when an old man takes the offensive quickly and smartly with a good cane, it generally has a very benficial and disturbing effect on a predator!! Knowing where and how to apply the cane makes a big difference. Training is available, both in person and online. Like all training, some is better than others, but it's worth a look! And you can take your cane places you can't take your EDC and you won't get a second look, especially if you walk like I do!!
