I don't even remember. I have a lot of swords and it was a really long time ago. As to why - I used to do a lot of medieval sword fighting stuff, and America can be a rough place. Someone banging on your door aggressively early in the morning usually doesn't have your best interests in mind, so it was an abundance of caution thing. I've long sense switched to answering the door with a giant cannister of pepper spray. Less likely to kill someone, much more effective at incapacitating cops, door to door salespeople, and large aggressive wildlife.
