Sir are you a licensed chef of good standing in OnlyChef's database? That knife is dangerous. We can issue you a government approved plastic version if you need to cut something, but SoylentGreen(tm) is Ready-to-Scoop(tm)!

Fun fact:

There is a law in California that has been interpreted to mean that all clubbing weapons are illegal. So if you by a length of pipe and keep it around (e.g. under your bed) explicitly for self-defense purposes, you have committed a crime.

IANAL, but as far as I can tell, keeping a shotgun in your home for self-defense purposes would be fine, as long as you aren't planning ahead of time to use it as a club.

[edit]

My information is slightly out-of-date; there was an injunction against enforcement in 2024 from Fouts v Bonta. I have no clue the injunction is or is not still in effect, so ask your lawyer before carrying a club.

They'll also have to ban motors and microcontrollers. As they can be used to build 3D printers and drones.

Maybe they'll ban Github, too - as it hosts unregulated open source software that can power these scary tools.

For a long time, you couldn’t buy “strike anywhere” matches because they could be used in producing meth.
