Une arme blanche

Meaning: A bladed weapon, as opposed to a firearm.

Literally: A white weapon

Example: “Selon les témoins, l'agresseur était armé d'une arme blanche.” — According to witnesses, the attacker was carrying a knife.

Origin: Blanc here means bare or unadorned polished steel, the same sense as in the older arme blanche for a drawn sword. The contrast is with arme à feu, the fire weapon.
