The Bolt Action Pen v.03 represents the culmination of everything INVENTERY has refined since bringing our entire production in-house. Where v.01 established the platform and v.02 perfected it, v.03 reimagines the Bolt Action Pen from the ground up — the most versatile and precise iteration to date.
At its core is an adjustable set screw: a quiet but defining feature that unlocks true refill versatility. With a single internal adjustment, the v.03 accommodates virtually any refill on the market — from Parker-style to Pentel Energel and everything in between — each dialed to its ideal length without swapping a single component. Paired with nose tips reamed to size (2.4mm / 2.5mm / 2.6mm), the v.03 eliminates the tip wiggle long associated with multi-refill pens. Engineered around the Energel for optimal length, yet genuinely refill-agnostic.
Completing the design is a refined step-nose profile and a single-piece barrel for cleaner lines and greater rigidity. Understated features, deliberately executed — the details you don't notice at first are the ones that change how the pen writes. In our eyes, the ultimate Bolt Action Pen in it's final form.
Available in 303 stainless steel, C693 brass, C145 copper, and 6Al-4v grade 5 titanium, 702 Zirconium.
