The Dimension Cutter is a device used to open portals to other dimensions. Please note that all dimension-cutting operations should be conducted in a large, open space. All personnel should tether themselves to a secure point before commencing. The manufacturers are not responsible for any discoveries made in parallel dimensions since this device is entirely the fictionalised imaginings of your own fevered brain.
One such device was used aboard Red Dwarf by JMC hologram Katerina Bartokovsky. (Back to Earth)
