I think that the moral of this story was that even if you are cut - that is not neccessarily the end - and that swords ceased to become viable weapons a long time ago.
The fact that the person in question survived the sword strike--that he was merely cut instead of being severed in two pieces--wasn't because the sword can't be an effective close-quarters weapon, but because the intended victim was just slightly out of range, hence he got a relatively shallow tip cut instead of being cut in half.
Inside 21 feet, person A with a holstered gun and person B with a sword in his hand, the swordsman will most likely win. Inside 15 feet, gun in hand probably wouldn't beat a sword if the swordsman was allowed to make the first move. Think Tueller drill with an extra 3 feet of reach...
Back to the original post--the sword is to the knife as the rifle is to the handgun--a much more effective and useful weapon, but not nearly as portable, hence most edged-weapon crimes are committed with concealable knives. (Not that that would stop the Australian .gov from banning swords, though.)
BTW, I have a good friend who is currently active-duty Army, holds a black belt in Isshinryu, and has studied the Japanese sword arts a bit. Once while stateside, he and his wife were awakened by a noise in the living room of their mobile home. He grabbed his katana and went to investigate, barefoot and in his underwear. The sight of a musclebound, underwear-clad martial artist swinging a katana must have put quite a fright into the burglar, because he broke the door on his way
out of the trailer. My friend chased the crook quite a ways down the gravel road (still barefoot and in his underwear) before the running-for-his-life crook finally got away...wish I could have been there for that...
