animal, and which is capable of inflicting death upon a human being
when used in the manner for which it was designed, except a bow and
arrow when possessed and used for hunting or any other lawful
purpose. Additionally, any instrument or device of any sort

that the defendant intends to inflict death or serious injury upon
the other, and which, when so used, is capable of inflicting death
upon a human being, is a dangerous weapon. Dangerous weapons include

other firearm, dagger, razor, stiletto, switchblade knife, knife
having a blade exceeding five inches in length, or any portable
device or weapon directing an electric current, impulse, wave, or
beam that produces a high-voltage pulse designed to immobilize a
person.
