A cold weapon is a weapon that does not rely on electricity or any other form of energy to function. Cold weapons include knives, swords, spears, and other handheld weapons that are used in close combat. These types of weapons have been used for thousands of years and are still in use in various parts of the world today. Cold weapons are often preferred in situations where the use of firearms or other energy-based weapons is not practical or allowed, such as in close quarters or in environments where the risk of accidental discharge is high. Cold weapons can also be used in sporting or recreational activities, such as fencing or historical reenactments.
