I understand where your coming from with the word weapon, but just as with many words these days the meaning has become corrupted, gay once meant happy and a bitch was a female canine.

A weapon, arm, or armament is any device used in order to inflict damage or harm to living beings, structures, or systems. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, and warfare. In a broader context, weapons may be construed to include anything used to gain a strategic, material or mental advantage over an adversary.
While just about any ordinary objects such as sticks, stones, cars, or pencils can be used as weapons, many are expressly designed for the purpose – ranging from simple implements such as clubs, swords and guns, and to complicated modern intercontinental ballistic missiles, biological and cyberweapons.
