Ko-Axis™ Rail Pen - Titanium Edition
Abandoning the cylindrical shape of a traditional pen, the Ko-Axis™ Rail Pen leverages the benefits of a flat, wide, rectangular geometry for unparalleled writing comfort and ultra-low profile carry.
Rather than cramping your fingers around a thin cylindrical shaft, you can embrace your writing instrument in a more natural way that provides long term comfort with less tension on your fingers. The 4-1/2" length is optimized to deliver a fluid writing experience in your hand, yet be incredibly compact for convenient everyday carry.
The magnetic twin-rail mechanism used to extend and retract the ink refill eliminates the need for a separate cap. Combined with an instant, no-tool refill replacement method, the Ko-Axis™ Rail Pen will always be your pen of choice. Its elegance, comfort, and simplicity will make you wonder why this never happened sooner.
This titanium edition has 25% more mass than its aluminum brother providing a solid and comfortable resilience that will last a lifetime, and is offered in a bead blasted Satin Matte finish or semi-stonewashed finish.

We've designed the Ko-Axis™ with a purpose-built, distinctive shape, sparing no detail. The comfort and ergonomics that were considered in the design phase are unparalleled, resulting in a truly unique writing experience. These features create an aesthetic that turns heads. All of these features have been packed into a pen so thin that it easily hides in any notebook. Be warned: once you write with the Ko-Axis™, you will never go back to a conventional pen.
Upon closer inspection of the Ko-Axis™ Rail Pen, you will discover that the aluminum grip slider contains the ink cartridge. By implementing this clever design, it is impossible for the pen to accidentally retract while writing. The ink refill is always present when you need it and never when you don't. We have painstakingly integrated eight ultra-strong neodymium magnets into the end stop positions to ensure perfect engagement, and eliminate any potential for movement of the mechanism while writing.
The Ko-axis™ isn’t just a beautiful writing instrument, it transforms the act of writing into a wonderful experience. From the first time you extend the ink refill, you’re hooked. The rectangular shape of the Ko-axis™ rests gently in the crease of your hand and lands comfortably in your thumb-and-finger pinch. The shallow divot in the aluminum slider offers the perfect spot for your pointer to land every time. The weight distribution of the pen was carefully calculated to rest in your hand without applying any torque to your fingers that would tire your hand in a late-night writing session. The Aluminum Edition is the featherlight member of the Ko-Axis™ family. The aluminum body allows the pen to float effortlessly across page after page. The Titanium Edition has 25% more mass than its aluminum brother, providing a solid and comfortable resilience that will last a lifetime. Every titanium model affords a rock-solid, stable action and exudes confidence in every word it writes.
