Microtech Siphon II Tactical Pen 4in Bronze Apocalyptic Stonewash MT401SSBKBZA

The Microtech Siphon II Black and Bronze Apocalyptic Pen blends precision machining, functional innovation, and bold styling into a writing instrument built to stand apart. Crafted from lightweight yet durable black aluminum, it’s accented with a rugged bronze stonewash finish that gives it a distinctive, battle-worn appearance. Instead of a standard click or twist mechanism, the Siphon II uses a unique lever system to deploy and retract the pen tip—a design that’s both intuitive and unmistakably Microtech.

Inside, it’s fitted with a pressurized Pilot G2 mini ink refill, ensuring smooth, reliable writing in a variety of conditions, whether you’re jotting notes at a desk or marking in the field. A sturdy pocket clip keeps it secure and accessible for daily carry, while its compact size—3.5 inches closed and 4 inches overall—makes it easy to slip into a pocket, pack, or organizer. At just 2.6 ounces, it’s light enough for everyday use without sacrificing a solid, balanced feel in hand.

Proudly made in the USA, the Siphon II reflects the same attention to detail and craftsmanship found in Microtech’s legendary knives, making it as much a collectible as a tool.
