Vortex manipulator

The Time Agency used wrist straps for a variety for functions, primarily&#160;to house a very basic form of time travel.&#160;According to the Time Agent John Hart, Time Agents would bicker over the size of their respective wrist straps. Although&#160;coming from the 51st century, they were shown to be&#160;of ordinary leather, as the explosion in the Torchwood 3&#160;hub&#160;neccesitated a new strap for it.
