Crafted from solid billet 6061 aircraft-grade aluminum, the PROOF Vanguard Pen is engineered for those who move with intention — and demand the tools they carry do the same. Its bolt-action mechanism is smooth, deliberate, and satisfying — a tactile nod to control in a world built on distraction. The Vanguard wasn't born in a boardroom. It began as a decade-old concept, revived by our lead designer as a hands-on build challenge — a personal test in machining, tolerancing, and technical mastery. What started as a training exercise became an obsession. The final result? A pen that had to exist.
