The Diplomat Slide Pen has a spring-loaded cartridge that wants to sit inside the pen's barrel. To deploy the tip you slide a shiny button on the outside of the pen down...
...and then across, to lock it in place. Slide the button back out of its locked position, and the tip snaps back into the pen.
The Slide comes with a little ball chain so you can hook it onto your keys.
