Toad, every single person on this board owns several knives, or at least live in a house that has several knives in it.
A great many people don't own guns, and don't live in a house with guns.
In other words, we can get along without guns, we can't get along without knives.
There have been attempts to ban certain types of knives, swords etc, and many campaigns by the press against them. They have foundered due to the fact it's very hard to classify what is a "normal" knife and what isn't. A Kukri might look impressive, but a long kitchen knife it's likely to be more deadly, if only for the fact it's probably made with better steel, and has a much better edge.
If knives were as effective a tool for killing people, then more murders in the US would be carried out with knives than guns, right? After all, there's no background check for knives, and they are a damn sight cheaper too.
Yet 5 times as many people are murdered with guns than knives in the US.
Guns are a modern meathod of defence as well, and I'd rather be armed when encountering some nutcase that wants to kill me or break into my house.
The vast majority of people who break in to houses are doing it to steal, not to kill. Of course, if they have a gun, and they think you have a gun, then they find themselves in the position of shoot or be shot. I doubt the fact that you are innocent, and they the criminal, matters much to them.
I'd much rather be unarmed in an unarmed society than armed in an armed society. After all, US policemen are all armed, and well trained as well. 50 of them get murdered on duty every year. British policemen are invariably unarmed, and approx 1 gets murdered every 5 years.
