The California Penal Code section 245(a)(1) (PC) defines a deadly weapon as any weapon or object that is either inherently deadly or used in a way that makes it capable of producing force likely to produce great bodily injury or death. While obvious examples include a knife, brass knuckles, or a tazer, a deadly weapon could also be a vehicle, boots, a screwdriver, a rock, or even a toaster oven used in a dangerous manner.
