Vibroweapons are weapons with the key function of rapid micro-vibrations that would enhance the cutting power of the weapons. Standard weapon types such as a sword or an axe could be given this function to transform them into even deadlier weapons. These weapons would easily cut through the standard iron, steel or bronze weapons and armours of Earth but could be brought to heel by alternate weapons such as energy-based weapons. These weapons are used extensively across the Perseus Arm, ever since the Medieval Era when they were abundant.
The weapons use a vibrogenerator to cause the blade to vibrate to such a degree that the micro-vibrations would add additional cutting power to the metal[Leg 1].
A vibroaxe is a vibroweapon shaped like an axe[Leg 1].
A vibrostaff is a vibroweapon in the form of a long staff[Leg 1].
A vibrolance is a vibroweapon in the form of a lance[Leg 2].
