Form follows function, and Lamy's Swift is evidence of this maxim. Cylindrical form and solid, spring-operated clip provide a double function: one click activates the refill for use, and simultaneously retracts the pocket clip into the body. Result? Smooth fluid writing, and no stained shirts. And if the clip is retracted, the Swift cannot be clipped into your pocket until you first retract the refill and reveal the clip. A perennial favorite.
