An unlawful attack by one person upon another for the purpose of inflicting severe or aggravated bodily injury. This type of assault usually is accompanied by the use of a weapon or by means likely to produce death or great bodily harm.
A weapon is any commonly known weapon (gun, knife, club, etc.) or any other item which, although not usually thought of as a weapon, becomes one in the commission of a crime. It is not necessary that injury result from an aggravated assault when a gun, knife or other weapon that could cause serious personal injury is used.
