That is similar here, we also have to have them in a safe. Pepperspray is allowed here as are many things that are banned in other countries. I know that in places like Canada you aren't allowed knives or knuckle dusters even if they are just as collector or show pieces, they are considered weapons.

If that was implemented here, it would simply mean that all the guns, knives and other miscellaneous weapons would belong to the criminals because they certainly aren't going to surrender their weapons and then crime would literally take over in a very short space of time. It's the wild west out here in South Africa.
