[QUOTE=Zuku;1269001]What is a dangerous weapon?
Section 1 of the Dangerous Weapons Act, 2013 (Act No 15 of 2013), defines a dangerous weapon as:
»» any object other than a firearm, capable of causing death or inflicting serious bodily harm, if it was used for an unlawful purpose.

The act leaves it to the discretion of the SAPS officer to decide if a "weapon" is dangerous. most EDC knives can be classified as dangerous weapons.

A good friends wife was the officer in command of one of the East Rand police stations. When they had to reach their crime / arrest quota's the easiest way would be to raid shebeens and confiscate knives.
