- Let's assume a person chooses a cutting weapon as a primary home defense weapon.
- Let's assume that same person picks something that makes at least some modicum of sense for the situation. e.g. Not a Claymore for a dwelling with small rooms, low ceilings and narrow halls.
- Let's assume this person does own firearms and there is nothing legally or obviously preventing the person from making the far more conventional choice of a firearm as a self-defense weapon.
- Let's assume that this person actually ends up in a home defense situation and uses the chosen primary home defense weapon to seriously injure or kill an attacker.
If I were that person, I would want to have given some serious thought, in advance, to what credible and socially acceptable answer I would give to the question of why I chose to chop someone up instead of using a gun for self-defense. Not because it's illegal to use a sword or axe or spear for self-defense but because I don't want anyone to get the idea that I chose such a weapon because I liked the idea of hacking on another human being with a large cutting weapon. I would want to give an explanation that would have some chance of explaining to a normal human being (who might have some input into determining if what I did was reasonable given the situation) why I picked that particular weapon. And I would want that explanation to leave no doubt that my motives didn't include getting a thrill out of cutting a human to pieces.
For example, let's say I am an avid saber fencing competitor. I think that it would make sense to someone that given my experience from competition I was very comfortable using a similar implement for self-defense.
Or perhaps, if I were to live in an apartment with people living all around, very close with only thin walls between, I could explain that I was concerned about the possibility of errant shots endangering my neighbors.
As a counterexample, let's say I had Kill Bill and SAW movie posters all over the house and no good reason for picking a sword over a shotgun. I think that could give someone the impression that I really enjoyed the idea of cutting a fellow human up and I think that impression would make most normal human beings pretty uncomfortable. Which isn't something I would want to do in a situation where someone's opinion could be very important.
Hypotheticals aside, I actually do have an edged weapon positioned for self-defense use--so I'm not saying it's automatically a bad idea. But I also have a good explanation--one that will make sense to a "normal person"--for why an edged weapon makes good sense for that situation.
