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.

Adam P. ★★★★★

The machining on this brass bolt is flawless—the threads engage with a satisfying precision that makes swapping refills a joy. I've had it for a week and the weight feels perfectly balanced in my hand for writing notes.

Elizabeth ★★★★★

Finally, a pen with some real heft—the polished brass feels substantial and the grip is perfectly balanced. The Pilot G2 refill fits smoothly, and the machining is flawless with no sharp edges. This thing writes like a dream and doubles as a discreet pocket tool.
