I was gonna mention Cajun Napalm, but Tat beat me to it.
I have a 14" hollow-ground carving knife at work. Razor sharp (I know, because I tested it the last time I used it, and now half of my left hand is bald). This thing would probably qualify as a short sword.
As to the original question, I wouldn't have had a moment's hesitation about loosing a little bacon on an intruder. Besides, I cook bacon in a cast iron skillet, which makes an impression "traditional blunt instrument", not to mention it would be hot as heck.
Honestly, I think about safety first and foremost when I'm in a kitchen.
