Rich,
When growing up in Hawaii, my grandpa took me to River Street when I was little..he'd visit all his old Chinatown cronies and introduced me to a side of Chinese life that I had not known. The bad thing was River Street was also the hangout for the pool hustlers, the street thugs, prostitutes, and the guys that came looking for things that you couldn't get on the "good" side.
One of my uncles told me of an incident that he had seen where my grandpa was waiting for the bus with his cane in hand. Three sailors thought they'd make fun of the ol'Chinaman. He ignored them until one of them tried to take his cane away from him. The ambulance had to take two of them away and the rest didn't remember too much except that old man kept "using that cane."
Some of you may remember that in a previous thread, I had mentioned that my grandfather had come to Hawaii with Sun-Yat Sen. My grandfather was one of the bodyguards for President Sun Yat Sen, one of the leaders who tried to introduce democracy to China before the communist takeover.
Anyway, my understanding is that in order to be a bodyguard, you had to beat all comers in combat....armed or unarmed, and the one left standing becomes one of the bodyguards.
Even at 77 years old and 80 pounds soaking wet, my grandfather easily beat my brother who had taken 8 years of martial arts.
So, yes, in the right hands a cane can be a very effective weapon. I am 52 and a cane sounds like a good tool to help me walk.
