Unlawful intent to use a weapon requires evidence that rules out lawful use.

Illinois’s per se dangerous weapon statute is not a strict liability offense and blade length is the length of any non-handle portion of a knife.

Charges for violation of Illinois’s possession with intent statute must include details of the intent to use it unlawfully.

Rainer v. State
763 S.W.2d 615 (Tex. 1989)

The blade length restriction in Texas law references the cutting portion of the knife, not the sharpened edge.
