The most light and comfortable of all the mouth machines, popular among wilderness explorers because of its singular purpose: pickling. The Saav's mechanical tongue processes matter both soft and hard without difficulty, feeding into a thermal chamber that flash-heats the substances, sundry, before they are sealed in tubes of acetic acid. Refined palates might object to the pungeal and viscous glop produced by this mouth machine. But those whose minds ferment in lower matters - pounding rocks, polishing rocks, peddling rocks - might gravitate towards the Saav due to its simple mechanism. Heat and acid are common solutions to unknown or noxious bacteria - reliable until the standard issue Sheleagh batteries corroded and the thermal chambers merely warmed the infusoria within. One might proffer this corrosion as the best possible explanation for the grisly end of the Coron-Tosam expedition, but one might also object to having one's fingers removed from one's hands by vengeful brutes. In any case, the secret is in the name: Sheleagh's Acetic Acid Ventures.
