In the world of Rifts Technology, there are simple blades which do damage to flesh and bone, but since everybody is wearing thick armor, technology has advanced to the point where a simple blade known as a Vibro-Blade can cut through steel like butter. Concealed within the handle is a power supply and electronics which vibrate the blade at hypersonic speeds which enables it to cut through dense materials. According to the supplemental Coalition War Machine, "...Vibro-blades are blade weapons surrounded by an invisible, high-frequency energy field that gives them mega-damage capabilities."
