Open Source "Rosie"
Rosies were not designed, but born of desperation. The first was created as part of a desperate fight for survival against an exsurgent monster aboard an Earth-Moon shuttle during the Fall. Rosies are made from heavy rivet guns, with a linear motor attached to the end. Rivets fired by the gun are given extra speed by the linear motor, up to ballistically useful velocities.

Wielding one electrode in each hand, an arc welder can be turned into a deadly, if awkward weapon. Almost as dangerous to wield as it is to fall victim to, electrochucks are used in gladiatorial entertainment or desperation. With capacitors on a belt or in a backpack, simultaneously touching both electrodes to a target causes a massive flow of electricity, often fatal, as well as severe electrical burns.

Research into industrial tools, high-energy physics and materials science often suggests weaponized spin-offs. Omnicor is an energy and materials-science oriented company, and has no established arms division, usually selling these ideas to companies like Direct Action or Gorgon Limited. One of the few exceptions is the sprinkler, a design that was simple and cheap enough to be worth manufacturing themselves. The sprinkler holds lead, heated just enough to be a liquid, which is then sprayed through a powerful electromagnetic field which accelerates and further heats the stream.
