Brass Bolt (Pilot G2 Configuration)
Fully-Machined, Polished Brass
The most recent version of the Brass Bolt maintains the original external geometry of the pen, while making small engineering adjustments to improve function. The internal o-ring on the lower body keeps the pen from unscrewing while being carried in a pocket. Changes to the J-slot include moving it upwards as far as it can go to keep the pen under 5.5 inches in length; and the J-slot itself has been rounded more dramatically to draw the bolt into place when actuating the refill. Machined from solid C360 free-machining brass that is then hand sanded and polished, after which a liquid oxidation agent is applied that temporarily protects against patination. Ships in our recyclable packaging with a custom vinyl sticker.
Comes pre-configured with a black 0.5mm Pilot G2 refill.

Our Bestseller
The Bolt wasn't our first pen, but it was the pen that changed everything in terms of machined writing instruments. From the Bolt Kickstarter campaign's massive success all the way up until today, the Bolt has remained our bestselling pen. Whether it's the unique style of the bolt-action combined with an easy-to-operate knob, the comfortable size, or the unique combinations of materials and colors; the Bolt is the pen that most people who've never seen our pens gravitate to. We continue to experiment with the Bolt to keep it fresh, most recently expanding to add a huge variety of machined grip profile options, like the Hive and Dragonskin pictured. We're hard at work on the next experiment, in the meantime, check out all of the available Bolt options, HERE.
