mitzip, no problem that it's OT, this is actually a nice hidden jewel in self-defense that gets a lot of discussion on other forums like THR.
Using a 3 foot stick as a weapon is older than dirt. It gives the user reach, hardness of impact, and mechanical acceleration or leverage. There are several martial arts that specifically have techniques dedicated to this type of stick. In Japanese arts, it's called a hanbō ("half staff") and has specific training regimens in aikido and some schools if ninjutsu. In the late 19th century there were several European schools of using walking sticks as weapons, and this actually ties it all together with the sword cane: In the renaissance up until the 18th century a gentleman almost always wore a sword, as both a personal accessory and a weapon of self-defense. Around that later time this started to fall out of fashion, and it was eventually replaced by the sword stick and then just the stick (likely due to concealed weapon laws). Victorian times are probably the most well known were men always had a stick, used to fend of feral dogs or street thugs.
Well I'm rambling a bit with that, so let me fast forward to right now. I have a variety of sticks I carry for self-defense. I make them but a few are bought. None are the hollow aluminum canes you get at a drug store. All are solid hardwood, though one is a special type of synthetic composite (Cold Steel City Stick). The most common mistake with choosing a cane is picking one with a big blunt weighted head, but a "unknown wood" shaft (usually a softwood like Pine or some unknown import from China). These are mediocre clubs at best, and will definitely break. My favorites have shafts of American Hornbeam (aka Ironwood or Musclewood), Chinese waxwood, hickory, jatoba, ash, oak, or purpleheart (if you don't mind the color). Some have metal heads, but others are all wood.
The cool thing about canes is you can take them anywhere due to how American law works. Because canes are medical devices, they cannot be restricted or taken away because of the Americans with Disabilities Act of 1990. And because of the Medical Privacy Act, you cannot be forced to say what your disability is (or if you even have one). And besides the law, imagine the social implications of a cop, guard, or business owner taking someone's stick or not letting them in. He or she might was well paint "Jerkwad" on their forehead.
