sorry, should say "carry", not "buy". most states have a maximum length you can carry (4-5.5 inches is common).
although, i would imagine at some length, it becomes a "sword" (even if marketed as a knife) and falls under some other "nanny"-ing. i have not googled that.

Doesn’t editing require a karma threshold?
it does not (thankfully!)
Apostrophe's don't have a karma threshold, either. ;-)
As kevin_thibedeau points out elsewhere in the thread, he's not necessarily wrong. In many states and foreign countries it's illegal to carry a large knife in public without a reason and I'm sure purchases are restricted in some places as well. Most people are more or less OK with that, it seems, so there historically hasn't been a lot of pushback.
So, having been given the proverbial inch (or centimeter), those obsessed with banning potentially-dangerous tools are trying to take the next mile (or kilometer): https://theconversation.com/why-stopping-knife-crime-needs-t...
