Boston knife ban?

First they came for my gun, and I did nothing. Then they came for my butter knife.

Also, Britain, I heard this is how the blades ban started in your country. Is that so, and should we Americans be concerned about this?

Because it only restricts the most dangerous blades that can easily do fatal harm to someone if used against them. In most sane areas of the US, this has almost always been the case. Much smaller non-fatal blades are still fine to use, however. In practice, pepper spray should be used if you're really concerned with defending yourself against attack, and I'll always be against those sorts of bans.
