A cold weapon (or white arm^[1][2]) is a weapon that does not involve fire or explosions (such as the act of combustion) as a result from the use of gunpowder or other explosive materials. Ranged weapons that do not include gunpowder or explosive materials and melee weapons are cold weapons. Firearms and explosives (such as grenades, land mines, missiles, bombs, etc.), and other weapons which rely on heat or burning are not cold weapons.
